Smoothing Dat The Estition Of Variance In Data
ESTIMATION OF VARIANCE IN HETEROSCEDASTIC DATA
Abstract
Data which exhibit none constant variance is considered. Smoothing procedures are applied to
estimate these none constant variances. In these smoothing methods the problem is to establish how
much to smooth. The choice of the smoother and the choice of the bandwidth are explored. Kernel
and Spline smoothers are compared using simulated data as well as real data. Although the two seem
to work very closely, Kernel smoother comes out to be slightly better.
KEY WORDS: Smoothing, Kernel, Spline, Heteroscedastic, Bandwidth, Variance. 1. Introduction

Given the errors are independently distributed. However if any of these assumptions are violated the
estimates obtained under the classical or usual assumption are not good. Therefore we hope to
obtain better estimates of when the estimation of the variance is incorporated.
Therefore, we need to investigate and incorporate the information about the variance estimates of
the errors which are needed for better understanding of the variability of the data. In heteroscedastic
regression models the variance is not constant. Often as in the case with the mean, the
heteroscedasity is believed to be in functional form which is referred to as variance function. We try
to understand the structure of the variances as a function of the predictors such as time, height, age
and so on. Two procedures of estimating the variance function includes the parametric and
nonparametric methods. The parametric variance function estimation may be defined as a type of
regression problem in which we see variance as a function of estimable quantities. Thus, the
heteroscedasticity is modeled as a function of the regression and other structural parameters. This
function is completely known, specified up to these unknown parameters. Estimation of these
parameters is what entails parametric methods.
However, for many practical problems the degree to which components of the statistical model can
be specified in a parametric form varies

Study of Profitability of a Logistics Company
STUDY OF PROFITABILITY OF A LOGISTICS COMPANY USING ECONOMETRICS TOOLS
Executive summary
This study examines the impact of three factors, namely Sales, Fixed assets and Interest paid on the
profitability of a logistics company. Econometric tool of multiple linear regression model was used
for analyzing the impact of above factors on profitability of a major logistics company GATI
Limited. Based on the financial data of last 10 years 2000–2009 the regression analysis has revealed
that profitability of GATI ltd. is significantly affected positively by increase in fixed assets and
adversely affected by increase in interest paid. The impact of increase in sales volume on
profitability is positive but miniscule. In addition seasonality ... Show more content on

Moreover, projects such as the Golden Quadrilateral program, National Maritime program, and
introduction of freight corridors in rails shall strengthen the growth. The current economic scenario,
which is largely impacted by the global slowdown however is expected to recover soon with the fall
in logistics costs due to the huge developments in infrastructure. With the rise in disposable
incomes, changing consumer preferences, fast emerging retail segments, infrastructure investment,
the Indian logistics sector and the 3PL markets are expected to witness explosive growth in the
successive years.
Constraints and Challenges
The biggest challenge faced by the organised logistics companies in India today, is competition from
the unorganized operators. This is coupled with increasing environmental pressures, government
regulations and subsidies for infrastructure development. Adding to all these, is the lack of "Industry
status" to the logistics sector.
Business Risks and Mitigation
The Year 2008–2009 for India was quite different from the expectations of industry stalwarts and
economy speculators. Increase in input materials costs, wages, interest and transportation forced
companies to cut costs. Logistic service providers therefore are required to be cost effective and
more efficient to compete in market place. High logistics and warehousing costs in India shows that

Unmanned Aerial Vehicles
Unmanned Aerial Vehicles (UAVs) also known as Remotely Piloted Vehicle (RPV) which can
operate without human operator, plays important role in both civilian and military purposes. [3]
[8]Weather reconnaissance, search and rescue assisting operations in sea and mountains, aerial
photographing and mapping, fire detection and traffic control are examples of usage fields. [1] Path
Planning, crucial phase for navigation process, is about to determining optimal or near optimal path
between destinations with fulfilling constraints such as hostile threats. [2] Depending on the degree
of difficulty of the task, operations such as path planning should be fulfilled without human support.
[1] The autonomy of such use is advantageous in situations that require quick decisions. And
success of path planning heavily relies on selected algorithm. [4] Measure of success can be
categorized into two sections: feasibility which considers to safely moving objects to target and
optimality which is about to finding optimal solution. When a task difficult to accomplish by a
single UAV or it is cheaper, easier or faster than there may be a need would arise to use multiple
UAVs to fulfill task [8]. To solve some problems multiple UAVs path planning may be came into as
a constraint. [8] Search and rescue operations are examples of multiple UAVs usage areas. There are
different types of path planning architectures. It can be centralized or distributed. In centralized

Basic Idea Of Smoothing : Basic Concepts Of Setting
2. Basic idea of smoothing
If is believed to be smooth, then the observation at , near should contain information about the value
of at . Thus it should be possible to use something like local average of data near to construct an
estimator of . Smoothing of a data set , involves the approximation of the mean response curve in
the regression relationship. The function of interest could be the regression curve itself, certain
derivatives of it or functions of derivatives such as extrema or inflection points.
In the trivial case in which is a constant, estimation of reduces to the point of location, since an
average over the response variables yields an estimate of . In practical studies though it is unlikely

This smoothing parameter regulates the size of the neighborhood around meaning a local average
over too large a neighborhood would cast away the good with the bad. In this situation an extremely
over smooth curve would be produced, resulting in a biased estimate . On the other hand defining
the smoothing parameter so that it corresponds to a very small neighborhood would not shift the
chaff from the wheat .Only a small number of observations would contribute none negligibly to the
estimate at making it very rough and wiggly. In this case the variability of would be inflated.
Finding the choice of smoothing parameter that balances the trade – off between over smoothing and
under smoothing is called the smoothing parameter selection problem.
3. Choosing the smoother
Some of the smoothing techniques include Kernel, Spline, Locally weighted regression, Recursive
Regressogram, Convolution, Median, Split linear fit and K–Nearest Neighbor among others. One of
the most active research areas in Statistics in the last 20 years has been the search for a method to
find the "optimal" bandwidth for a smoother. There are now a great number of methods to do this.
Unfortunately none of them is fully satisfactory. Here a comparative study of the two mostly used
and easy to implement smoothers is presented. The Kernel and the cubic spline smoothers .The
comparison is preformed on a simulated data set. Looking at

Using Adaptive Response Surface Regression
3 Methodology
The developed optimisation routine makes use of adaptive response surface regression to use a
limited initial amount of FE models to feed an optimisation routine which is specifically designed
for general thermal problems where parameters linked to the general heat equation can be optimised
or estimated using experimental input data. The algorithm uses a pan and zoom function to move
through the design space and delivers faster predictions with fewer iterations than standard updating
routines [35, 41].
3.1 Adaptive response surface method
The adaptive response surface optimisation routine is used to optimise numerical models with a lot
of data points and the time reducing by the algorithm increases as the number of parameters rises
[40]. The routine is designed to handle multiple–output time series data [35]. The optimisation
procedure can be divided into following steps:
1. Starting reference simulation points are ran and a correct object function is built of the difference
between the FE model and the target value (experiment or validation model).
2. The FE model is replaced by a meta–model of response surfaces to decrease the optimisation time
but remains an accurate approximation.
3. The optimisation routine is run on a specific object function. It is possible to use multiple
objective functions or build an objective function related to multiple outputs.

What Is An Interpolation Equation

1. 1 Interpolation:
First of all, we will understand that what the interpolation is.
Interpolation is important concept in numerical analysis. Quite often functions may not be available
explicitly but only the values of the function at a set of points, called nodes, tabular points or pivotal
points. Then finding the value of the function at any non–tabular point, is called interpolation.
Definition:
Suppose that the function f (x) is known at (N+1) points (x0, f0), (x1, f1), . . . , (xN, fN) where the

Narrative Reflection
Friends, families, and colleagues frequently ask me about the classes I am taking in my doctoral
program. For most of the classes, they just smile and nod while feigning interest and that is the
extent of our conversation on the topic. However, when I tell them that I am taking a "statistics"
course, the most common reaction is a wide–eyed look with a grimace formed on their countenance.
The usual comments are, "Statistics sucks!", "I'm terrible at math!", or "You poor thing!". I just
smile, because I have a little secret...I really enjoyed the two statistics classes I have had so far, 702
and 873. I LOVE math and taught middles school math for eight years, so getting to take a class that
involves getting to use my math skills and enjoyment of analysis of data makes me giddy. Now,
don't get me wrong, this doesn't mean that several times this semester I didn't feel totally
overwhelmed and wanted to pull my hair out while banging my head on the counter. I was there!
THE most rewarding part of attempting something difficult and challenging is the point where the
lightbulb comes on and understanding (or partial understanding with some concepts) is FINALLY
reached. Overall, my experience in 873 was exciting because it was challenging and now I have a
better understanding of statistics and I have developed further skills for analyzing and using data.
These are important gains as data analysis is a big part of what I do in my job as an elementary

Choose The Appropriate Joinery Technique When Building...
To: ENGL–315–45 Classmates
From: CJ Peterson
Subject: How to Choose the Appropriate Joinery Technique when building wood furniture
Date: April 6, 2016
Many people want to build their own furniture and other wood projects, but aren't sure how to start.
Different types of projects require different types of joinery, but your average Do–It–Yourselfer
(DIYer) can do most beginner projects.
It may seem overwhelming to many of you to take on a new task such as building your very own
furniture. Choosing the wrong joint could lead to additional unnecessary steps, weaken the object,
and cause premature failure of the furniture. Alternatively, it could just plain look unattractive – a
thing to be avoided for sure.
Choosing the appropriate joinery technique is quite simple as long as you follow the appropriate
steps. I have been building furniture and remodeling homes for eight years, which means I have
done quite a bit of woodworking. I am hoping to share this experience with my classmates so that
they can reach the very attainable goal of building their own furniture.
A good place to begin is to identify the main joints, consider what uses each is best used for, and
examine your own ability to execute each. These joints have all been around for a long time; they
have been tested in numerous applications. In this report, I highlight some of the main joints and
their applications.

ABSTRACT: This case exposes students to the application of regression analyses to be used as a
tool pursuant to understanding cost behavior and forecasting future costs using publicly available

by Continental as a result of the recent financial crisis and the challenges it faces to remain

Continental's internal forecasts indicated that a further decline in passenger volume should be
anticipated throughout 2009, with a recovery in travel possibly occurring by the middle of 2010.
To summarize, adverse economic conditions in the U.S., coupled with the rise in fuel costs, were
dragging down Continental's profits and relief was unlikely through the foreseeable future.
THE DECISION TO REDUCE FLYING CAPACITY AND THE IMPACT ON
OPERATING COSTS
Given the situation described above, management needed to act swiftly to restore profitability.
Several strategic options were evaluated. Since the U.S. and much of the world was facing a severe
recession, the prospect for growing revenues by either raising airfares or passenger volume seemed
futile. Contrary to raising revenue, Continental's managers believed that raising fares could
potentially erode future revenues beyond the present level. Discounting fares did not seem a
plausible solution either, because given the severity of the economic situation a fare cut could fall
short in stimulating additional passenger demand and lead to lowering revenues.
Thus, because management anticipated that revenues would remain flat for most of the year, the
only viable short–term solution to restoring profits was a substantial and swift reduction in operating
costs. This could most effectively be accomplished in two ways. First, through a reduction in flying

Image Processing Essay
Abstract: – A Measurement is must before going to the further calculations in various fields of work
or study. In order to find out something we definitely need some calculations. In different sectors,
determining exact size and shape are progressively becoming an issue and based on that the latency
is going up. As we cannot measure everything with a scale or a tape, we use some optical methods
of Image Processing. In this paper, we present an approach that can be used to determine the lengths
and some other degrees of measurements like diameter, spline, Caliper(perpendicular angle) etc. We
used mostly the Image Processing techniques because all the measurements are done on an Image.
We also use some other techniques like Euclidean ... Show more content on Helpwriting.net ...
The image can be enhanced to mark down the accurate end points. It actually can mark the end of a
single pixel which is almost invisible as a single pixel to the naked eye. A set of operations need to
be carried out respectively to achieve this. Initially the image need to be acquired and smoothened to
mark the pixel actually need to be. Then the neighborhood pixels collision should be eliminated
followed by the image segmentation. Finally, using the Euclidean algorithm the exact length can be
found.
II. IMAGE AQUSITION AND SMOOTHING: –
In Image Processing mostly the initial step will be the Image acquisition and smoothing. As the
input for the tool of any Image Processing technique is an image, the input image should be taken
and enhanced in all the ways possible. Enhancement involves smoothing the image, grey scaling,
removing the unwanted blur, differentiating the subject from background and so on. In this project,
for enhancing or smoothing the image we use the median filter. The median filter is non–linear
digital filtering technique where the noise reduction is the pre–processing step before going to the
further processing. Because the signal is big in the case of images, we chose median filter as it can
handle the larger signal and the run–time is literally less. The major advantage of the median filter is
the edge preservation. It processes each signal individually and replaces the edges of the pixel with

Notes On The And Flow Data
2 DATAAND OPERATIONALIZATION
Tostudy the impactofpoliticalaffinity onFDI,I employ the datafrom UNCTAD,whichrecord bilateral
FDI stock and flow data for more than 200 countries from 2001 to 2012. Since FDI flow data can be
a poor conceptual choice for answering political questions (Kerner, 2014;
Sorens and Ruger, 2015; Benacek et al., 2014), I choose to use only the stock data.
One possible drawback for UNCTAD data is its compilation by reports from different countries,
which have varied reporting rules and rigorousness. As a result, it may have serious measurement
errors or substantial missing values. However, this weakness appears to plague the other two major
FDI data resources (IMF and OECD) as well. 1 In addition, since biased or ... Show more content on

This choice is mainly out of convenience. It is also workable to use the outstock data instead. The
interpretation will be similar.
2.1 POLITICAL AFFINITY
Admittedly there is no perfect measure for two countries' political closeness. To somehow proxy this
measurement, I use the ideal points compiled by Erik Voeten and colleagues from the UN general
assembly roll–call voting data. 3 This dataset has ideal point estimates for countries from 1946 to
2014. To measure political affinity for a given country pair, I take the absolute value of the
difference between their ideal points and code them as "idealPoint". In this regard, the smaller value
the idealPoint variable is, they closer is the country pair's relationship.
2.2 CONTROLS
As mentioned before, to somehow mitigate the reporting country's biasness, I need to apply controls
over the country's general FDI volume. More importantly, the volume of FDI stock in a certain
country is substantially affected by the attractiveness of the destination and the financial caliber of
the donor country. In this regard, I tally the total volume of both the instock FDI for the recipient
country and the outstock FDI for the donor country. The former is used as a proxy for the
destination's investment attractiveness and the latter for the donor's financial caliber. This way I can
sidestep the use of other economic controls and focus on studying how political affinity affect FDI.

These labels were combined to produce an initial non–background binary mask. We then used the

step operation on the initial mask: dilate by one voxel, fill holes with face connectivity and erode by
one voxel in each dimension. Such an operation resulted a solid mask for the brain only region.
Structures outside the mask were stripped to generate the brain images. An additional bias field
inhomogeneity correction algorithm was performed based on the N3 algorithm [#Sled1998] using
the c3d tool. CUMC: 12 images were acquired on a 1.5 T Siemens scanner by the Columbia
University Medical Center. These images had relatively large variations in contrast. 128 class labels
were provided covering detailed brain structures. This dataset was used for evaluation in

Nt1310 Unit 3 Assignment 1 Study Guide
All substates of $S_{1,L_2}$ describe the actual mating process. $S_{3,L_3}$ describes the first
contact between the spline shaft and its socket. $C_U$ of $C_{3,L_2}$ is defined that the acting
forces and torques are above the sensor noise level and that there is a nearly constant $z$–position.
$C_R$ demands that both workpieces have not been in contact before. So the state $S_{3,L_3}$ or
$ll$textit{firstContact}$gg$ describes how the spline shaft is inserted into the socket. The end of
the mating task is represented by state $S_{4,L_3}$ or $ll$textit{finalMating}$gg$. For being in
this state, $C_{4,L_2}$ requires a high $z$–force peak and after that a constant $z$–position.
Another substate is $S_{2,L_3}$ or $ll$textit{preBlocking}$gg$ and this substate is discussed in
detail during the description of the online fault detection in

The first is named $S_{6,L_3}$ or $ll$textit{break}$gg$. In order to be in this state,
$C_{6,L_2}$ has to be fulfilled and this condition requires a constant $z$–position and constant
forces and torques. It is defined by the domain expert that a constant $z$–position and changing
forces and torques are equal to the condition $C_{5,L_2}$. The corresponding state is named
$S_{5,L_3}$ or $ll$textit{blocking}$gg$. This is a very interesting state because it contains a
problem during task execution. On higher decomposition levels, the substates of this state also
describe how the problem was handled in order to solve it. But on higher levels, the domain expert
has to be aware of the maximal human movement frequency in order to identify intended human
actions. If a state does not take enough time, it can represent an intended movement. So the domain

External Estimates

External Estimates of the Number of Abortions Pooled and by Individual Year
The counts of the total number of abortions for the study period years come from published
information from the Guttmacher Institute's census of abortion providers (Finer and Henshaw 2003;
Jones and Kavanaugh 2011). Following prior research, I used the CDC's age distribution for each
year to calculate the expected number of abortions that occurred in the age distribution of Add
Health for each year, except in the years when an age distribution was collected by the Guttmacher
Institute's survey of abortion patients (Kost and Jones 2007; Fu et al. 1998). Because the CDC data
is provided in ages ranges (under 15; 15–19; 20–24; 25–29; 30–34; 35–39; 40+), the Add Health
data was restricted to best match these ranges (see Appendix 2 for further details).
The overall quality analyses (years 1994 through 2007) could potentially include pregnancies
between the ages of 10 (the youngest individuals in Wave 1 in 1994) and 32 (the oldest individuals
in Wave 4 in 2008). Though it should be noted that pregnancies under the age of 13 would be
somewhat improbable considering the median age of menarche in the U.S. is 12.43 ... Show more

For example, in 2005 women in the Add Health sample would be between 21 and 30. Women 30
and over were excluded from the analyses and the comparison group was aged–matched based upon
the CDC estimates for women aged 20–24 and 25–29. Spline and linear interpolated age estimates
from the Guttmacher Institute's survey of abortion patients were compared with the estimates used

Fonte et al in 2006 [3] Suggested that Most of catastrophic mechanical failures in power rotor shafts
occur under cyclic bending combined with steady torsion: Mode I (ΔKI) combined with Mode III
(KIII). An analysis of the influence of steady torsion loading on fatigue crack growth rates in shafts
is presented for short as well as long cracks. Long cracks growth tests have been carried out on
cylindrical specimens in DIN Ck45k steel for two types of testing: rotary or alternating bending
combined with steady torsion in order to simulate real conditions on power rotor shafts. The growth
and shape evolution of semi–elliptical surface cracks, starting from the cylindrical specimen surface,
has been measured for several loading conditions and both testing types. Short crack growth tests
have been carried out on specimens of the same material DIN Ck45k, under alternating bending
combined with steady torsion. The short crack growth rates obtained are compared with long crack
growth rates. Results have shown a significant reduction of the crack growth rates when a steady
torsion Mode III is superimposed to cyclic Mode I. A 3D Finite Element analysis has also shown
that Stress Intensity Factor values at the corner crack surface depend on the steady torsion value and
the direction of the applied torque. Citarella et al in 2010 [4] Worked on Comparison of DBEM and

Random Forest, An Ensemble Learning Algorithm
3. ALGORITHM BASIS 3.1. Random forest The random forest is an ensemble learning algorithm
that combines the ideas of bootstrap aggregating [20] and random subspace method [21] to
construct randomized decision trees with controlled variation, introduced by Breiman [22].
According to the theory of random forest algorithm, for a collection of classifiers h1(x), h2(x), . . . ,
hK(x), and with the training set at random from sampled random vector Y, X, the margin function is
termed as: (1) where, I(.) represents the indicator function. This margin function measures the extent
to which the fraction of correct classifications exceeds the fraction of the most voted incorrect
classifications. The generalization error is given as: (2) where, the probability is over the space X, Y.
This depends upon the strength of the individual weak learners in the forest and the correlation
between them. By definition, in random forests, (3) Therefore, the margin function for a random
forest would be: (4) And the expected strength of the classifiers in a random forest is: (5) The
fundamental idea of the random forest is that at each tree split, a random sample of m features is
drawn, and only those m features are considered for splitting, where m = √N, N being total number
of features. For each tree grown on a bootstrap sample, the out–of–bag strength is monitored. The
forest is then re–defined based on this out–of–bag strength by de–correlating the irrelevant trees.

The History Of Geographic Information Systems ( Gis )
Introduction:
Recent research on interpolation of climatological and meteorological information with the support
of Geographic Information Systems (GIS) has shown that interpolation has a large development
potential within climatology and meteorology. At the same time the demand for interpolated data
products are increasing, numerical weather models are working at higher spatial resolutions and may
be initiated by gridded data from observations. Interpolation is a method of getting new data from
some known data points. In India, many weather data is from official departments and there are
many weather sites, but in some areas it is difficult to obtain weather data, so we will use
interpolation methods to get climate data of that areas. Interpolation can be defined as the estimation
of an unknown value of the variable, at some point where no measurement is available, where the
estimate is made using known measurements obtained at a set of sample locations. With the advent
of Geographic Information Systems (GIS), numerous spatial interpolation methods have been
applied to create continuous surfaces of climate variables at various spatial (watershed, regional, and
global) and temporal (hourly, daily, monthly, seasonal, and annual) scales. The prediction of weather
condition is essential for various applications. Like weather prediction, soil moisture, climate data
monitoring, rainfall, population prediction, agriculture, image processing etc. Regression model,

An Evaluation Of An Innovative Contribution Of My Work
Research Statement Mohamad S Hasan Modern technological advancements in automated data
production have produced a large increase in the scale and resolution of data sets. In a statistical
context, more information generates more hypothesis tests and opens new dimensions to discover
the targeted questions. However, many of the tests are redundant and, hence, reduce the efficiency of
the analysis. One potential solution to this problem is using external information to prioritize the
hypothesis tests most likely to yield true positive effects. One means of doing so is p–value
weighting. Many statistical methods have been proposed to up–weight and down–weight the p–
value in a multiple hypotheses setting. None of them are satisfactory, which necessitate extensive
research in this area. My methodological and theoretical research as well as a considerable portion
of my applied work addresses this issue with regard to high throughput and big data. An innovative
contribution of my work is the establishment of a new perspective on the analysis of high
throughput data for which relative effect sizes are very low and the true effect is hard to detect with
the usual statistical analysis, although external sources of information suggests otherwise. We
proposed a method referred to as Novel Optimal P–value weighting for High Throughput Data.

Components Of The Clutch Pack
There are three components that forms the clutch assembly. They are the clutch pack, one way
clutch and the band. These components help in the gear shifting and to have a smooth driving.
CLUTCH PACK The clutch pack contains alternating disks that fit inside a clutch drum in which
half of the discs are made up of steel. These disks have splines which fit inside the clutch drum on
the respective groves. The other half consists of a friction material bonded to their surface. These
disks also have splines but on the inner side which fit into the groves on the outer surface of the
adjoining hub. At appropriate times, the clutch pack is squeezed together by a piston which is
present inside the clutch drum that is activated by oil pressure so that the two components become
locked and turn as one. ONE WAY CLUTCH One way clutch is a device which have the effect just
like that of a bicycle, where it allows a component to turn freely in one direction but not in the other.
One way clutch is also called as sprang clutch. This is mainly used in ring gear so that it will not
turn in opposite direction. One way clutch is commonly used in the first gear. For example, place the
gear shifter in drive position and give acceleration. The vehicle begins to move normally and when
the acceleration is released the vehicle continues to move freely as if the vehicle is in neutral.

Abstract
Wireless sensor networks (WSN) are self– governing sensors that are widely distributed in the
respective environment. They are also referred as wireless sensor and actuator networks (WSAN).
They are used to observe physical or environmental conditions, for example, temperature, sound,
natural activities etc. They collect data from each active node and pass it to the network to the
centralized location. There are many flaws occurred in wireless sensor network like user
authentication as well as data travel in the network is not so much secure. We are developing a
technique in which firstly we are allowing the user to pass the hard security authentication scheme
and then the user can join the network. Further we are also providing a secure file transmission in
network via public and private key concept. In this way we maintain the secure and authenticated
transmission of data in predescribed environment.

Smoothing Dat The Estition Of Variance In Data
ESTIMATION OF VARIANCE IN HETEROSCEDASTIC DATA
Abstract
Data which exhibit none constant variance is considered. Smoothing procedures are applied to
estimate these none constant variances. In these smoothing methods the problem is to establish how
much to smooth. The choice of the smoother and the choice of the bandwidth are explored. Kernel
and Spline smoothers are compared using simulated data as well as real data. Although the two seem
to work very closely, Kernel smoother comes out to be slightly better.

Given the errors are independently distributed. However if any of these assumptions are violated the
estimates obtained under the classical or usual assumption are not good. Therefore we hope to
obtain better estimates of when the estimation of the variance is incorporated.
Therefore, we need to investigate and incorporate the information about the variance estimates of
the errors which are needed for better understanding of the variability of the data. In heteroscedastic
regression models the variance is not constant. Often as in the case with the mean, the
heteroscedasity is believed to be in functional form which is referred to as variance function. We try
to understand the structure of the variances as a function of the predictors such as time, height, age
and so on. Two procedures of estimating the variance function includes the parametric and
nonparametric methods. The parametric variance function estimation may be defined as a type of
regression problem in which we see variance as a function of estimable quantities. Thus, the
heteroscedasticity is modeled as a function of the regression and other structural parameters. This
function is completely known, specified up to these unknown parameters. Estimation of these
parameters is what entails parametric methods.
However, for many practical problems the degree to which components of the statistical model can
be specified in a parametric form varies

Theory The pixel time profiles in cardiac MRI are extremely organized when we have perfect gating
and breath–holding. Some penalties for example; temporal Fourier sparsity (to exploit low temporal
bandwidth), temporal total variation (to exploit smooth pixel time profiles) or low–rank penalties (to
exploit the redundancy between the pixel time profiles) can be utilized to make the recovery from
under sampled data well posed. However, the compactness of the signal representations will be
extensively degraded in the presence of inter–frame motion, which can emerge due to breathing or
inconsistent gating; because of which, the performance of the above schemes will be extensively
compromised. We propose to defeat the above limitation by ... Show more content on

The regularization term in Eq. (1) promotes the sparsity of the deformation corrected dataset〖 T〗
_θ.L, instead of L. Here, Φ(u) indicates an arbitrary prior to exploit the redundancy in the data; λ is
the corresponding regularization parameter. The primary advantage of the proposed algorithm is that
it can be utilized with any spatio–temporal priors on the deformation corrected dataset. The
particular priors can be chosen relying upon the particular application. The capability of the
algorithm to handle arbitrary image priors makes this methodology definitely different from
classical motion compensation algorithms that register each frame to a specific fully sampled frame.
The deformation field in Eq. (1) is assumed to be parametrically represented in terms of the
parameters. For example, Θ is the set of B–spline coefficients if a B–spline model is used to
represent the deformation field as in [24] and [25]. In this case, the spatial smoothness of the
deformation map is controlled by the grid spacing of the B–spline map. The spatial smoothness
requirements can also be explicitly forced using regularization constraints on the deformation field
as in [26]. Our approach is closely related to [26]. We suggest to use a variable splitting approach
[27], [28] to decouple the original problem in (1) to simpler sub problems. Specifically, we split the

factors, namely site conditions, schedule constraints, project scope, and constructability issues could
play an important role either in preventing the CO or reducing the chances of needing a big

Questions On The Equation For Regression
Question 3–Results Question 3. The following equation was deduced from the Heredia, (2015)
question 3, and it was based on the equation for regression. These are the results: Ӯ=b+mx or
Ӯ=mx+b, Ӯ= dependent variableoverall, a= constant b, b1=predictor 1GRE score on
quantitative b value, x1 = GRE score on quantitative. b2=predictor 2GRE score on verbal b value,
x2=GRE score on verbal. B3=predictor 3ability to interact easily b value, x3=ability to interact
easily. Equation– Ӯ=a+b1(x1) +b2(x2) +b3(x3) Overall college GPA=2.250+0.002 (GRE,
quantitative+0.028(ability to interact). Step 1–If the model is significant with a significant value of
0.014, less than 0.05. High F value (3.907), lower significance value (.014). Step 2=Amounted

Smoothing Dat The Estition Of Variance In Data

  • 1. Smoothing Dat The Estition Of Variance In Data ESTIMATION OF VARIANCE IN HETEROSCEDASTIC DATA Abstract Data which exhibit none constant variance is considered. Smoothing procedures are applied to estimate these none constant variances. In these smoothing methods the problem is to establish how much to smooth. The choice of the smoother and the choice of the bandwidth are explored. Kernel and Spline smoothers are compared using simulated data as well as real data. Although the two seem to work very closely, Kernel smoother comes out to be slightly better. KEY WORDS: Smoothing, Kernel, Spline, Heteroscedastic, Bandwidth, Variance. 1. Introduction Let us have the observations .The mean is given by , . The deviations of each observation away ... Show more content on Helpwriting.net ... Given the errors are independently distributed. However if any of these assumptions are violated the estimates obtained under the classical or usual assumption are not good. Therefore we hope to obtain better estimates of when the estimation of the variance is incorporated. Therefore, we need to investigate and incorporate the information about the variance estimates of the errors which are needed for better understanding of the variability of the data. In heteroscedastic regression models the variance is not constant. Often as in the case with the mean, the heteroscedasity is believed to be in functional form which is referred to as variance function. We try to understand the structure of the variances as a function of the predictors such as time, height, age and so on. Two procedures of estimating the variance function includes the parametric and nonparametric methods. The parametric variance function estimation may be defined as a type of regression problem in which we see variance as a function of estimable quantities. Thus, the heteroscedasticity is modeled as a function of the regression and other structural parameters. This function is completely known, specified up to these unknown parameters. Estimation of these parameters is what entails parametric methods. However, for many practical problems the degree to which components of the statistical model can be specified in a parametric form varies ... Get more on HelpWriting.net ...

Study of Profitability of a Logistics Company STUDY OF PROFITABILITY OF A LOGISTICS COMPANY USING ECONOMETRICS TOOLS Executive summary This study examines the impact of three factors, namely Sales, Fixed assets and Interest paid on the profitability of a logistics company. Econometric tool of multiple linear regression model was used for analyzing the impact of above factors on profitability of a major logistics company GATI Limited. Based on the financial data of last 10 years 2000–2009 the regression analysis has revealed that profitability of GATI ltd. is significantly affected positively by increase in fixed assets and adversely affected by increase in interest paid. The impact of increase in sales volume on profitability is positive but miniscule. In addition seasonality ... Show more content on Helpwriting.net ... Moreover, projects such as the Golden Quadrilateral program, National Maritime program, and introduction of freight corridors in rails shall strengthen the growth. The current economic scenario, which is largely impacted by the global slowdown however is expected to recover soon with the fall in logistics costs due to the huge developments in infrastructure. With the rise in disposable incomes, changing consumer preferences, fast emerging retail segments, infrastructure investment, the Indian logistics sector and the 3PL markets are expected to witness explosive growth in the successive years. Constraints and Challenges The biggest challenge faced by the organised logistics companies in India today, is competition from the unorganized operators. This is coupled with increasing environmental pressures, government regulations and subsidies for infrastructure development. Adding to all these, is the lack of "Industry status" to the logistics sector. Business Risks and Mitigation The Year 2008–2009 for India was quite different from the expectations of industry stalwarts and economy speculators. Increase in input materials costs, wages, interest and transportation forced companies to cut costs. Logistic service providers therefore are required to be cost effective and more efficient to compete in market place. High logistics and warehousing costs in India shows that there are ...

Unmanned Aerial Vehicles Unmanned Aerial Vehicles (UAVs) also known as Remotely Piloted Vehicle (RPV) which can operate without human operator, plays important role in both civilian and military purposes. [3] [8]Weather reconnaissance, search and rescue assisting operations in sea and mountains, aerial photographing and mapping, fire detection and traffic control are examples of usage fields. [1] Path Planning, crucial phase for navigation process, is about to determining optimal or near optimal path between destinations with fulfilling constraints such as hostile threats. [2] Depending on the degree of difficulty of the task, operations such as path planning should be fulfilled without human support. [1] The autonomy of such use is advantageous in situations that require quick decisions. And success of path planning heavily relies on selected algorithm. [4] Measure of success can be categorized into two sections: feasibility which considers to safely moving objects to target and optimality which is about to finding optimal solution. When a task difficult to accomplish by a single UAV or it is cheaper, easier or faster than there may be a need would arise to use multiple UAVs to fulfill task [8]. To solve some problems multiple UAVs path planning may be came into as a constraint. [8] Search and rescue operations are examples of multiple UAVs usage areas. There are different types of path planning architectures. It can be centralized or distributed. In centralized systems; a universal path planer ... Get more on HelpWriting.net ...

Thus it should be possible to use something like local average of data near to construct an estimator of . Smoothing of a data set , involves the approximation of the mean response curve in the regression relationship. The function of interest could be the regression curve itself, certain derivatives of it or functions of derivatives such as extrema or inflection points. In the trivial case in which is a constant, estimation of reduces to the point of location, since an average over the response variables yields an estimate of . In practical studies though it is unlikely that the ... Show more content on Helpwriting.net ... This smoothing parameter regulates the size of the neighborhood around meaning a local average over too large a neighborhood would cast away the good with the bad. In this situation an extremely over smooth curve would be produced, resulting in a biased estimate . On the other hand defining the smoothing parameter so that it corresponds to a very small neighborhood would not shift the chaff from the wheat .Only a small number of observations would contribute none negligibly to the estimate at making it very rough and wiggly. In this case the variability of would be inflated. Finding the choice of smoothing parameter that balances the trade – off between over smoothing and under smoothing is called the smoothing parameter selection problem. 3. Choosing the smoother Some of the smoothing techniques include Kernel, Spline, Locally weighted regression, Recursive Regressogram, Convolution, Median, Split linear fit and K–Nearest Neighbor among others. One of the most active research areas in Statistics in the last 20 years has been the search for a method to find the "optimal" bandwidth for a smoother. There are now a great number of methods to do this. Unfortunately none of them is fully satisfactory. Here a comparative study of the two mostly used and easy to implement smoothers is presented.

Using Adaptive Response Surface Regression 3 Methodology The developed optimisation routine makes use of adaptive response surface regression to use a limited initial amount of FE models to feed an optimisation routine which is specifically designed for general thermal problems where parameters linked to the general heat equation can be optimised or estimated using experimental input data. The algorithm uses a pan and zoom function to move through the design space and delivers faster predictions with fewer iterations than standard updating routines [35, 41]. 3.1 Adaptive response surface method The adaptive response surface optimisation routine is used to optimise numerical models with a lot of data points and the time reducing by the algorithm increases as the number of parameters rises [40]. The routine is designed to handle multiple–output time series data [35]. The optimisation procedure can be divided into following steps: 1. Starting reference simulation points are ran and a correct object function is built of the difference between the FE model and the target value (experiment or validation model). 2. The FE model is replaced by a meta–model of response surfaces to decrease the optimisation time but remains an accurate approximation. 3. The optimisation routine is run on a specific object function. It is possible to use multiple objective functions or build an objective function related to multiple outputs. 4.

For most of the classes, they just smile and nod while feigning interest and that is the extent of our conversation on the topic. However, when I tell them that I am taking a "statistics" course, the most common reaction is a wide–eyed look with a grimace formed on their countenance. The usual comments are, "Statistics sucks!", "I'm terrible at math!", or "You poor thing!". I just smile, because I have a little secret...I really enjoyed the two statistics classes I have had so far, 702 and 873. I LOVE math and taught middles school math for eight years, so getting to take a class that involves getting to use my math skills and enjoyment of analysis of data makes me giddy. Now, don't get me wrong, this doesn't mean that several times this semester I didn't feel totally overwhelmed and wanted to pull my hair out while banging my head on the counter. I was there! THE most rewarding part of attempting something difficult and challenging is the point where the lightbulb comes on and understanding (or partial understanding with some concepts) is FINALLY reached. Overall, my experience in 873 was exciting because it was challenging and now I have a better understanding of statistics and I have developed further skills for analyzing and using data. These are important gains as data analysis is a big part of what I do in my job as an elementary principal. When I do ... Get more on HelpWriting.net ...

To: ENGL–315–45 Classmates From: CJ Peterson Subject: How to Choose the Appropriate Joinery Technique when building wood furniture Date: April 6, 2016 Many people want to build their own furniture and other wood projects, but aren't sure how to start. Different types of projects require different types of joinery, but your average Do–It–Yourselfer (DIYer) can do most beginner projects. It may seem overwhelming to many of you to take on a new task such as building your very own furniture. Choosing the wrong joint could lead to additional unnecessary steps, weaken the object, and cause premature failure of the furniture.

ISSUES IN ACCOUNTING EDUCATION Vol. 26, No. 1 2011 pp. 181–200 American Accounting Association DOI: 10.2308/iace.2011.26.1.181 A Case Study on Cost Estimation and Profitability Analysis at Continental Airlines Francisco J. Román ABSTRACT: This case exposes students to the application of regression analyses to be used as a tool pursuant to understanding cost behavior and forecasting future costs using publicly available data from Continental Airlines. Specifically, the case focuses on the harsh financial situation faced by Continental as a result of the recent financial crisis and the challenges it faces to remain profitable. It then highlights the importance of reducing and controlling costs as a viable strategy to restore ... Show more content on Helpwriting.net ... Continental's internal forecasts indicated that a further decline in passenger volume should be anticipated throughout 2009, with a recovery in travel possibly occurring by the middle of 2010. To summarize, adverse economic conditions in the U.S., coupled with the rise in fuel costs, were dragging down Continental's profits and relief was unlikely through the foreseeable future. THE DECISION TO REDUCE FLYING CAPACITY AND THE IMPACT ON OPERATING COSTS Given the situation described above, management needed to act swiftly to restore profitability. Several strategic options were evaluated. Since the U.S. and much of the world was facing a severe recession, the prospect for growing revenues by either raising airfares or passenger volume seemed futile. Contrary to raising revenue, Continental's managers believed that raising fares could potentially erode future revenues beyond the present level. Discounting fares did not seem a plausible solution either, because given the severity of the economic situation a fare cut could fall short in stimulating additional passenger demand and lead to lowering revenues. Thus, because management anticipated that revenues would remain flat for most of the year, the only viable short–term solution to restoring profits was a substantial and swift reduction in operating costs. This could most effectively be accomplished in two ways. First, through a reduction in flying ... Get more on HelpWriting.net ...

In order to find out something we definitely need some calculations. In different sectors, determining exact size and shape are progressively becoming an issue and based on that the latency is going up. As we cannot measure everything with a scale or a tape, we use some optical methods of Image Processing. In this paper, we present an approach that can be used to determine the lengths and some other degrees of measurements like diameter, spline, Caliper(perpendicular angle) etc. We used mostly the Image Processing techniques because all the measurements are done on an Image. We also use some other techniques like Euclidean ... Show more content on Helpwriting.net ... The image can be enhanced to mark down the accurate end points. It actually can mark the end of a single pixel which is almost invisible as a single pixel to the naked eye. A set of operations need to be carried out respectively to achieve this. Initially the image need to be acquired and smoothened to mark the pixel actually need to be. Then the neighborhood pixels collision should be eliminated followed by the image segmentation. Finally, using the Euclidean algorithm the exact length can be found. II. IMAGE AQUSITION AND SMOOTHING: – In Image Processing mostly the initial step will be the Image acquisition and smoothing. As the input for the tool of any Image Processing technique is an image, the input image should be taken and enhanced in all the ways possible. Enhancement involves smoothing the image, grey scaling, removing the unwanted blur, differentiating the subject from background and so on. In this project, for enhancing or smoothing the image we use the median filter. The median filter is non–linear digital filtering technique where the noise reduction is the pre–processing step before going to the further processing. Because the signal is big in the case of images, we chose median filter as it can handle the larger signal and the run–time is literally less. The major advantage of the median filter is the edge preservation. It processes each signal individually and replaces the edges of the pixel with ... Get more on HelpWriting.net ...

However, interacting with multimedia data, and video in particular, requires more than connecting with data banks and delivering data via networks to customers, homes or offices. We still have limited tools and applications to describe, organize, and manage video data. The fundamental approach is to index video data and make it a structured media.

Notes On The And Flow Data 2 DATAAND OPERATIONALIZATION Tostudy the impactofpoliticalaffinity onFDI,I employ the datafrom UNCTAD,whichrecord bilateral FDI stock and flow data for more than 200 countries from 2001 to 2012. Since FDI flow data can be a poor conceptual choice for answering political questions (Kerner, 2014; Sorens and Ruger, 2015; Benacek et al., 2014), I choose to use only the stock data. One possible drawback for UNCTAD data is its compilation by reports from different countries, which have varied reporting rules and rigorousness. As a result, it may have serious measurement errors or substantial missing values. However, this weakness appears to plague the other two major FDI data resources (IMF and OECD) as well. 1 In addition, since biased or ... Show more content on Helpwriting.net ... This choice is mainly out of convenience. It is also workable to use the outstock data instead. The interpretation will be similar. 2.1 POLITICAL AFFINITY Admittedly there is no perfect measure for two countries' political closeness. To somehow proxy this measurement, I use the ideal points compiled by Erik Voeten and colleagues from the UN general assembly roll–call voting data. 3 This dataset has ideal point estimates for countries from 1946 to 2014. To measure political affinity for a given country pair, I take the absolute value of the difference between their ideal points and code them as "idealPoint". In this regard, the smaller value the idealPoint variable is, they closer is the country pair's relationship. 2.2 CONTROLS As mentioned before, to somehow mitigate the reporting country's biasness, I need to apply controls over the country's general FDI volume. More importantly, the volume of FDI stock in a certain country is substantially affected by the attractiveness of the destination and the financial caliber of the donor country. In this regard, I tally the total volume of both the instock FDI for the recipient country and the outstock FDI for the donor country. The former is used as a proxy for the destination's investment attractiveness and the latter for the donor's financial caliber. This way I can sidestep the use of other economic controls and focus on studying how political affinity affect FDI. 3This dataset can be downloaded from Harvard. ... Get more on HelpWriting.net ...

It was compared to two related registration methods and three state–of–the–art methods in terms of accuracy, solution regularity and computational cost. Subsection{Data} 5 public available brain MR image datasets (BrainWeb, CUMC, IBSR, LPBA, OASIS) were selected in our experiments. These datasets have been used in image registration projects [#Klein2009, #Ou2014, #Hellier2001, #Rohlfing2012] for performance evaluation. In these datasets, the whole head was captured by a variety of imaging scanners and protocols. Accordingly, images had different size, voxel spacing and contrast level. All images were provided with corresponding label ... Show more content on Helpwriting.net ... These labels were combined to produce an initial non–background binary mask. We then used the c3d tool provided by the ITK–SNAP package [#Yushkevich2006] to sequentially perform a three– step operation on the initial mask: dilate by one voxel, fill holes with face connectivity and erode by one voxel in each dimension. Such an operation resulted a solid mask for the brain only region. Structures outside the mask were stripped to generate the brain images. An additional bias field inhomogeneity correction algorithm was performed based on the N3 algorithm [#Sled1998] using the c3d tool. CUMC: 12 images were acquired on a 1.5 T Siemens scanner by the Columbia University Medical Center. These images had relatively large variations in contrast. 128 class labels were provided covering detailed brain structures. This dataset was used for evaluation in [#Klein2009] and a cached copy http://www.synapse.org/#!Synapse:syn3217817 was maintained by the author of [#Klein2009].

Nt1310 Unit 3 Assignment 1 Study Guide All substates of $S_{1,L_2}$ describe the actual mating process. $S_{3,L_3}$ describes the first contact between the spline shaft and its socket. $C_U$ of $C_{3,L_2}$ is defined that the acting forces and torques are above the sensor noise level and that there is a nearly constant $z$–position. $C_R$ demands that both workpieces have not been in contact before. So the state $S_{3,L_3}$ or $ll$textit{firstContact}$gg$ describes how the spline shaft is inserted into the socket. The end of the mating task is represented by state $S_{4,L_3}$ or $ll$textit{finalMating}$gg$. For being in this state, $C_{4,L_2}$ requires a high $z$–force peak and after that a constant $z$–position. Another substate is $S_{2,L_3}$ or $ll$textit{preBlocking}$gg$ and this substate is discussed in detail during the description of the online fault detection in Subsec.~ref{subsec:OnlineFaultDetection}.

The first is named $S_{6,L_3}$ or $ll$textit{break}$gg$. In order to be in this state, $C_{6,L_2}$ has to be fulfilled and this condition requires a constant $z$–position and constant forces and torques. It is defined by the domain expert that a constant $z$–position and changing forces and torques are equal to the condition $C_{5,L_2}$. The corresponding state is named $S_{5,L_3}$ or $ll$textit{blocking}$gg$. This is a very interesting state because it contains a problem during task execution. On higher decomposition levels, the substates of this state also describe how the problem was handled in order to solve it. But on higher levels, the domain expert has to be aware of the maximal human movement frequency in order to identify intended human actions.

External Estimates Measures from External Estimates External Estimates of the Number of Abortions Pooled and by Individual Year The counts of the total number of abortions for the study period years come from published information from the Guttmacher Institute's census of abortion providers (Finer and Henshaw 2003; Jones and Kavanaugh 2011). Following prior research, I used the CDC's age distribution for each year to calculate the expected number of abortions that occurred in the age distribution of Add Health for each year, except in the years when an age distribution was collected by the Guttmacher Institute's survey of abortion patients (Kost and Jones 2007; Fu et al. 1998). Because the CDC data is provided in ages ranges (under 15; 15–19; 20–24; 25–29; 30–34; 35–39; 40+), the Add Health data was restricted to best match these ranges (see Appendix 2 for further details). The overall quality analyses (years 1994 through 2007) could potentially include pregnancies between the ages of 10 (the youngest individuals in Wave 1 in 1994) and 32 (the oldest individuals in Wave 4 in 2008). Though it should be noted that pregnancies under the age of 13 would be somewhat improbable considering the median age of menarche in the U.S. is 12.43 ... Show more content on Helpwriting.net ... For example, in 2005 women in the Add Health sample would be between 21 and 30. Women 30 and over were excluded from the analyses and the comparison group was aged–matched based upon the CDC estimates for women aged 20–24 and 25–29. Spline and linear interpolated age estimates from the Guttmacher Institute's survey of abortion patients were compared with the estimates used to test the robustness of these analyses, and no significant differences were found when comparing the 95% confidence intervals (see Appendix 3A and Appendix 3B).

Fonte et al in 2006 [3] Suggested that Most of catastrophic mechanical failures in power rotor shafts occur under cyclic bending combined with steady torsion: Mode I (ΔKI) combined with Mode III (KIII). An analysis of the influence of steady torsion loading on fatigue crack growth rates in shafts is presented for short as well as long cracks. Long cracks growth tests have been carried out on cylindrical specimens in DIN Ck45k steel for two types of testing: rotary or alternating bending combined with steady torsion in order to simulate real conditions on power rotor shafts. The growth and shape evolution of semi–elliptical surface cracks, starting from the cylindrical specimen surface, has been measured for several loading conditions and both testing types. Short crack growth tests have been carried out on specimens of the same material DIN Ck45k, under alternating bending combined with steady torsion. The short crack growth rates obtained are compared with long crack growth rates. Results have shown a significant reduction of the crack growth rates when a steady torsion Mode III is superimposed to cyclic Mode I. A 3D Finite Element analysis has also shown that Stress Intensity Factor values at the corner crack surface depend on the steady torsion value and the direction of the applied torque.

According to the theory of random forest algorithm, for a collection of classifiers h1(x), h2(x), . . . , hK(x), and with the training set at random from sampled random vector Y, X, the margin function is termed as: (1) where, I(.) represents the indicator function. This margin function measures the extent to which the fraction of correct classifications exceeds the fraction of the most voted incorrect classifications. The generalization error is given as: (2) where, the probability is over the space X, Y. This depends upon the strength of the individual weak learners in the forest and the correlation between them. By definition, in random forests, (3) Therefore, the margin function for a random forest would be: (4) And the expected strength of the classifiers in a random forest is: (5) The fundamental idea of the random forest is that at each tree split, a random sample of m features is drawn, and only those m features are considered for splitting, where m = √N, N being total number of features.

The History Of Geographic Information Systems ( Gis ) Introduction: Recent research on interpolation of climatological and meteorological information with the support of Geographic Information Systems (GIS) has shown that interpolation has a large development potential within climatology and meteorology. At the same time the demand for interpolated data products are increasing, numerical weather models are working at higher spatial resolutions and may be initiated by gridded data from observations. Interpolation is a method of getting new data from some known data points. In India, many weather data is from official departments and there are many weather sites, but in some areas it is difficult to obtain weather data, so we will use interpolation methods to get climate data of that areas. Interpolation can be defined as the estimation of an unknown value of the variable, at some point where no measurement is available, where the estimate is made using known measurements obtained at a set of sample locations. With the advent of Geographic Information Systems (GIS), numerous spatial interpolation methods have been applied to create continuous surfaces of climate variables at various spatial (watershed, regional, and global) and temporal (hourly, daily, monthly, seasonal, and annual) scales. The prediction of weather condition is essential for various applications.

An Evaluation Of An Innovative Contribution Of My Work Research Statement Mohamad S Hasan Modern technological advancements in automated data production have produced a large increase in the scale and resolution of data sets. In a statistical context, more information generates more hypothesis tests and opens new dimensions to discover the targeted questions. However, many of the tests are redundant and, hence, reduce the efficiency of the analysis. One potential solution to this problem is using external information to prioritize the hypothesis tests most likely to yield true positive effects. One means of doing so is p–value weighting. Many statistical methods have been proposed to up–weight and down–weight the p– value in a multiple hypotheses setting. None of them are satisfactory, which necessitate extensive research in this area. My methodological and theoretical research as well as a considerable portion of my applied work addresses this issue with regard to high throughput and big data. An innovative contribution of my work is the establishment of a new perspective on the analysis of high throughput data for which relative effect sizes are very low and the true effect is hard to detect with the usual statistical analysis, although external sources of information suggests otherwise. We proposed a method referred to as Novel Optimal P–value weighting for High Throughput Data. Many studies have that suggested diverse methodologies regarding the p–value weighting.

These components help in the gear shifting and to have a smooth driving. CLUTCH PACK The clutch pack contains alternating disks that fit inside a clutch drum in which half of the discs are made up of steel. These disks have splines which fit inside the clutch drum on the respective groves. The other half consists of a friction material bonded to their surface. These disks also have splines but on the inner side which fit into the groves on the outer surface of the adjoining hub. At appropriate times, the clutch pack is squeezed together by a piston which is present inside the clutch drum that is activated by oil pressure so that the two components become locked and turn as one. ONE WAY CLUTCH One way clutch is a device which have the effect just like that of a bicycle, where it allows a component to turn freely in one direction but not in the other. One way clutch is also called as sprang clutch. This is mainly used in ring gear so that it will not turn in opposite direction. One way clutch is commonly used in the first gear.

Therefore, we need to investigate and incorporate the information about the variance estimates of the errors which are needed for better understanding of the variability of the data. In heteroscedastic regression models the variance is not constant. Often as in the case with the mean, the heteroscedasity is believed to be in functional form which is referred to as variance function. We try to understand the structure of the variances as a function of the predictors such as time, height, age and so on. Two procedures of estimating the variance function includes the parametric and nonparametric methods. The parametric variance function estimation may be defined as a type of regression problem in which we see variance as a function of estimable quantities. Thus, the heteroscedasticity is modeled as a function of the regression and other structural parameters. This function is completely known, specified up to these unknown parameters. Estimation of these parameters is what entails parametric methods. However, for many practical problems the degree to which components of the statistical model can be specified in a parametric form varies ... Get more on HelpWriting.net ...

A Relationship Between The Height Of Waitutu Forest Trees Bivariate 3.9: Waitutu Forest Saplings Problem I am going to investigate if there is a relationship between the height of Waitutu forest saplings, and their width (measured at breast height). Both the explanatory variable and the response variable are measured in centimetres. This data was taken from randomly selected trees in study plots of either 1.5 hectares or 2.25 hectares of the Waitutu Forest in the summer. The data was published by the Landcare research NZ.ltd in the Waitutu Forest, Southland 2001–2008. I think that the data will show a positive relationship in that as the height of the sapling increases, so will the width. Plan I am carrying out this investigation as Waitutu Forest is one of new Zealand 's largest forests, covering 45,000 hectares of South East Fiordland and is part of the National park. According to the Department of Conservation, The Waitutu forest is one of the largest areas of unmodified lowland forest left in the country. The unique build of the landscape consists of marine terraces and gullied terrain. The species of plant analysed in this dataset were sub–canopy (large shrubs or small trees), Broadleaf forest trees, and podocarp forest trees. The study of undergrowth and young saplings allows understanding of growth and how each plant develops, therefore allowing us to aid the continuation of the very significant Waitutu forests, and therefore protecting our native flora and fauna.

In order to show the benefit of using the proposed piecewise registration framework, we compared the proposed approach to a nonlinear registration using a global DCT nonlinear model. To demonstrate the performance change caused by replacing the linear model with the nonlinear model in a piecewise registration framework, we compared the proposed approach to a piecewise affine registration approach. In addition, to evaluate the standing of the proposed approach, we compared it to three established registration methods: a) the SyN method [#Avants2008] provided in the Advanced Normalization Tools (ANTs) software package http://http://stnava.github.io/ANTs.

Each of such parameter files was recommended with usage scenario, we could select from existing configurations to get the best of Elastix. Third, the selected Elastix configuration used the cubic B–Splines based model. Thus, the Elastix method can be considered as a published implementation using a B–Splines based global nonlinear model. When it was compared to the proposed approach with the piecewise B–Splines model, we could evaluate the gain of using the piecewise framework.

Some penalties for example; temporal Fourier sparsity (to exploit low temporal bandwidth), temporal total variation (to exploit smooth pixel time profiles) or low–rank penalties (to exploit the redundancy between the pixel time profiles) can be utilized to make the recovery from under sampled data well posed. However, the compactness of the signal representations will be extensively degraded in the presence of inter–frame motion, which can emerge due to breathing or inconsistent gating; because of which, the performance of the above schemes will be extensively compromised. We propose to defeat the above limitation by ... Show more content on Helpwriting.net ... The regularization term in Eq. (1) promotes the sparsity of the deformation corrected dataset〖 T〗 _θ.L, instead of L. Here, Φ(u) indicates an arbitrary prior to exploit the redundancy in the data; λ is the corresponding regularization parameter. The primary advantage of the proposed algorithm is that it can be utilized with any spatio–temporal priors on the deformation corrected dataset. The particular priors can be chosen relying upon the particular application. The capability of the algorithm to handle arbitrary image priors makes this methodology definitely different from classical motion compensation algorithms that register each frame to a specific fully sampled frame. The deformation field in Eq. (1) is assumed to be parametrically represented in terms of the parameters. For example, Θ is the set of B–spline coefficients if a B–spline model is used to represent the deformation field as in [24] and [25]. In this case, the spatial smoothness of the deformation map is controlled by the grid spacing of the B–spline map. The spatial smoothness requirements can also be explicitly forced using regularization constraints on the deformation field as in [26]. Our approach is closely related to [26]. We suggest to use a variable splitting approach [27], [28] to decouple the original problem in (1) to simpler sub problems. Specifically, we split the deformation from the l_1 norm by introducing an auxiliary variable g. This enables us to reformulate the unconstrained ... Get more on HelpWriting.net ...

Linear Regression is a data analysis deliberated for computing the association between two variables by connecting a linear equation to perceive information (Christensen, et al, 2014). An individual enters data points into the calculator and the computer retains the course of the calculations and completes the essential calculations for linear regression (Christensen, et al, 2014). Linear Regression is a method for displaying the straight–line relationship between variables by using a linear equation to observed data. Regression analysis is a collection of statistical procedures used to explain or predict the values of a dependent variable founded on the standards of one or more independent or predictor variables. (Christensen, et al, 2014). The two main kinds of regression analysis are called simple regression, in which there is a single independent or predictor variable, and multiple regression, in which there are two or more independent or predictor variables (Christensen, et al, 2014). The straightforward notion of regression analysis is to acquire the regression equation, and this calculation outlines the regression line that best fits the pattern of reflection in the ...

According to Gunhan and Arditi (2007), there were three types of contingencies, namely designer's contingency, contractor's contingency, and owner's contingency. They claimed that the best method to predict contingency was to use previous experiences. They mentioned that a detailed study of four factors, namely site conditions, schedule constraints, project scope, and constructability issues could play an important role either in preventing the CO or reducing the chances of needing a big contingency money. Smith et al. (1999) stated that the wise decision on the amount of contingency used while bidding could have effects on whether wining of the contract. They interviewed 12 contractors on the contingency calculation method and found that among these contractors, nobody was aware of any kind of estimation method for the contingency amount. Whenever, these contractors used contingency, they simply followed the traditional approach of adding some percentages to the base cost as contingencies. Mac and Picken (2000) conducted a study on two types of projects, namely estimating using risk analysis (ERA) and non–ERA projects. They made comparison between 45 ERA projects with 287 non–ERA projects and found that ERA method helped to reduce the unnecessary risk allowances in projects.

Inside the range of the diagram the prediction might be accurate. So we can tell very precisely how much the car is going to cost in the next few years, but we won't be able to give a very precise prediction on how much the car is going to cost after a long term (more than 10 years).

Implementation the COLE algorithm on the GPU is memory–intensive due to the potential large number of point scatterers. A large number of point scatterers mean that a large amount the process of memory needs to be processed, that is, memory bandwidth can be a limiting factor. Outline of the primary parts of the COLE calculation. Each point scatterer is anticipated onto the imaging line with an anticipated sufficiency that relies upon the sidelong and elevational remove. After projection, the RF flag is gotten by convolving with a heartbeat waveform. The scatterers are here attracted with zone corresponding to their outright dissipating adequacy. The anticipated adequacy is reflected in the quality of the circle curves.
