Data Science - Part X - Time Series ForecastingDerek Kane
This lecture provides an overview of Time Series forecasting techniques and the process of creating effective forecasts. We will go through some of the popular statistical methods including time series decomposition, exponential smoothing, Holt-Winters, ARIMA, and GLM Models. These topics will be discussed in detail and we will go through the calibration and diagnostics effective time series models on a number of diverse datasets.
Since the CAPM model Sharpe (1965) and the first “fundamental” model by King (1966) the use of “factors” in alpha generation and risk modeling has become mainstream. However, the types of factors we employ and the techniques we use to model relationships have in general not progressed much since. In addition, many of our favorite techniques assume that the world is static, whereas of course markets evolve and change dramatically; as we have seen so vividly illustrated over the last few years.
We review fundamental, macro-economic, and statistical factors, describing the advantages and disadvantages of each, and review some newer techniques that explicitly allow for evolving relationships in data sets and harness emerging technologies that can capture much more nuanced relationships than simple correlation: “flexible” least-squares regression, artificial immune systems, single-pass clustering, semantic clustering, social network influence measurement, layer-embedded networks, block-modeling, and more.
This document provides an introduction to econometrics. It defines econometrics as the application of statistical and mathematical techniques to economic data in order to test economic theories and models. The document outlines the methodology of econometrics, including stating an economic theory, specifying mathematical and econometric models, obtaining data, estimating models, hypothesis testing, forecasting, and using models for policy purposes. It also discusses the structure of economic data such as time series, cross-sectional, and panel data. Finally, it covers key econometric concepts like the categories of variables and the differences between ratio and interval scales.
The document provides an overview of quantitative techniques in analysis including different levels of measurement, common statistical software packages, and different types of data that can be analyzed such as time series data, cross-sectional data, and panel data. It discusses nominal, ordinal, interval, and ratio levels of measurement and how they are treated in SPSS. Examples of time series, cross-sectional, and panel data are also provided to illustrate the concepts.
Analyzing The Term Structure Of Interest Rates Using The Dynamic Nelson Siege...Dawn Cook
This document summarizes a discussion paper that introduces time-varying parameters into the dynamic Nelson-Siegel model for analyzing the term structure of interest rates. Specifically, it allows the factor loadings in the Nelson-Siegel model to vary over time using step functions and spline functions, and introduces time-varying volatility specified as a spline function of time. Estimating the model on U.S. Treasury yield data, it finds the time-varying specifications significantly improve model fit compared to the standard dynamic Nelson-Siegel model which assumes constant loadings and volatility. It also illustrates how the model can handle an unbalanced dataset with missing observations.

Case Study 1
Structure and Function of the Respiratory System
Brad is 45 years old and has been working as a coal cutter in a mine for the last 25 years. He likes the job because it pays well and the same mine had employed his father. Like many of his colleagues, Brad has had problems with a chronic cough. He has avoided his annual checkups for fear that he will be told he has “black lung,” or coal worker’s pneumoconiosis. The disease causes fibrosis, decreased diffusing capacity, and permanent small airway dilation. In later stages, pulmonary capillaries, alveoli, and airways are destroyed.
How can the disease described above create a mismatch between ventilation and perfusion? Use your understanding of alveolar dead space and physiologic shunt to explain your answer.
Individuals with chronic obstructive pulmonary disease have more difficulty exhaling than inhaling. Why is this so?
In general terms, what mechanisms in lung disease can affect diffusing capacity across alveolar membranes? Use the Fick law to explain your answer.
Case Study 2
Respiratory Tract Infections, Neoplasms, and Childhood Disorders
Patricia was called at work by a woman at the local daycare center. She told Patricia to come and pick up her son because he was not feeling well. Her son, three-and-a-half-year-old Marshall, had been feeling tired and achy when he woke up. While at daycare, his cheeks had become red and he was warm to touch. He did not want to play with his friends, and by the time Patricia arrived, he was crying. Later that afternoon, Marshall’s condition worsened. He had fever, chills, a sore throat, runny nose, and a dry hacking cough. Suspecting Marshall had influenza, Patricia wrapped him up and took him to the community health care clinic.
Why did Marshall’s presentation lead Patricia to think he had influenza and not a cold? Why is it important to medically evaluate and diagnose a potential influenza infection?
Describe the pathophysiology of the influenza virus. Outline the properties of influenza A antigens that allow them to exert their effects in the host.
Marshall may be at risk at contracting secondary bacterial pneumonia. Why is this so? Explain why cyanosis may be a feature associated with pneumonia.

Requirements:
Make sure all of the topics in the case study have been addressed.
Cite at least three sources; journal articles, textbooks or evidenced-based websites to support the content.
All sources must be within 5 years.
Do not use .com, Wikipedia, or up-to-date, etc., for your sources.
Case Study 1
Structure and Function of the Respiratory System
Brad is 45 years old and has been working as a coal cutter in a mine for the last 25 years. He likes the job because it pays well and the same mine had employed his father. Like many of his colleagues, Brad has had problems with a chronic cough. He has avoided his annual checkups for fear that he will be told he has “black lung,” or coal worker’s pneumoconiosis. The disease causes fibrosis, decreased diffusing capacity, and permanent small airway dilation. In later stages, pulmonary capillaries, alveoli, and airways are destroyed.
How can the disease described above create a mismatch between ventilation and perfusion? Use your understanding of alveolar dead space and physiologic shunt to explain your answer.
Individuals with chronic obstructive pulmonary disease have more difficulty exhaling than inhaling. Why is this so?
In general terms, what mechanisms in lung disease can affect diffusing capacity across alveolar membranes? Use the Fick law to explain your answer.
Case Study 2
Respiratory Tract Infections, Neoplasms, and Childhood Disorders
Patricia was called at work by a woman at the local daycare center. She told Patricia to come and pick up her son because he was not feeling well. Her son, three-and-a-half-year-old Marshall, had been feeling tired and achy when he woke up. While at daycare, his cheeks had become red and he was warm to touch. He did not want to play with his friends, and by the time Patricia arrived, he was crying. Later that afternoon, Marshall’s condition worsened. He had fever, chills, a sore throat, runny nose, and a dry hacking cough. Suspecting Marshall had influenza, Patricia wrapped him up and took him to the community health care clinic.
Why did Marshall’s presentation lead Patricia to think he had influenza and not a cold? Why is it important to medically evaluate and diagnose a potential influenza infection?
Describe the pathophysiology of the influenza virus. Outline the properties of influenza A antigens that allow them to exert their effects in the host.
Marshall may be at risk at contracting secondary bacterial pneumonia. Why is this so? Explain why cyanosis may be a feature associated with pneumonia.

How to Manage Reception Report in Odoo 17Celine George
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

TIME SERIES MODELS FOR FORECASTING NEW ONE-
FAMILY HOUSES SOLD IN THE U.S.Comment by

INTRODUCTIONComment by InformationServices:
Introduction
The housing market has been weak since its recent peak in
2005. Then, the sharp drop in the housing prices in 2007
contributed to the subprime loan crisis [1]. This dramatic
change in the housing market not only affects the construction
industry, but also may have a significant impact on the whole
economy [3]. We are still in the midst of the housing problem
with the increase in the delinquency rate and foreclosure rate.
In this paper, time-series models are specified to forecast new
one-family houses sold in the U.S. Through this research, we
try to predict the future development of this housing market.
THE DATA PATTERN OF NEW ONE-FAMILY HOUSES
SOLD IN THE U.S.Comment by InformationServices: The data
pattern
Figure 1 shows the time-series data for the non-seasonally
adjusted monthly new one-family houses sold (NHS) in the U.S.
from January 1975 to January 2010, the most recent data
available. The period is chosen to be long enough to reveal the
cyclical fluctuations in this market. A time series is normally
contain some or all of the following components, (1) trend, the
long-term change in the level of the data, (2) seasonality, a
regular variation in the level of the data that repeats itself at the
same time every year, (3) cycles, wavelike fluctuations of the
data around the trend, and (4) irregularity, the remaining and
random variation in the data. From the figure, we can see that
the NHS data have significant seasonality, cycles, and upward
trend till 2005. Comment by InformationServices: The figure

In evaluating a time-series data, it is useful to analyze the
autocorrelation which measures the correlation between
successive observations over time. A k-period plot of
autocorrelations is called an autocorrelation function (ACF). A
12-period plot of autocorrelation function for the NHS data and
24-period plot of ACF for the first differenced NHS data from
January 1975 to June 2009, the historical period in our analysis,
are shown in Figures 2 and 3. In figure 2, all ACFs are
significantly different from zero because they are above the
upper limit level and slowly decreasing, this implies there is a
trend in the NHS data. In figure 3, ACFs for lag 12 and 24 are
above the upper limit level which means they are significantly
different from zero. This confirms seasonality in this monthly
data.Comment by InformationServices: ACF analysis

TIME-SERIES MODELS FOR NEW ONE-FAMILY HOUSES
SOLDComment by InformationServices: Time-series model
selection based on the data pattern. You can also include a
regression model in your paper.
Since the NHS data have trend and seasonality, three time-
series models are chosen for estimation and forecasting
purposes: Winter’s exponential smoothing, the decomposition,
and the autoregressive integrated moving average (ARIMA) [4].
The data from January 1975 to June 2009 as the historical
period are used for model specification. The next six months
from July 2009 to December 2009 are chosen as the holdout
period in which the actual data are available so we can compare
with ex-post forecast to evaluate the accuracy of models.
Comment by InformationServices: Separate the historical and
holdout periods
Excel-based Forecast X software is used for estimation and
forecasting [2]. In order to compare how good the estimated
values fit the original data, two error measurements, the mean
absolute percentage error (MAPE) and the root-mean-squared
error (RMSE) are calculated and shown in table 1. To obtain
15. MAPE, we first divide the forecast error or error (actual value –
forecast value) by the actual value to yield the percentage error
and then calculate the mean of the absolute percentage errors.
For RMSE, we first square the forecast error and then take the
squared root of the mean of the squared errors.Comment by

*Mean of NHS for the historical period is 61.46 and for the

The best model should be the one with the smallest error.
Among these three time-series models, the decomposition with
exponential smoothing trend has the smallest MAPE and RMSE
for both historical period and holdout period. Therefore, we use
this model and the data from January 1975 to December 2009 to
perform the ex-ante point and interval forecasts for the first six
months of 2010 as show in table 2 and figure 4. Comment by

IS THE WORST OVER?
People would like to know whether the worst of this housing
market downturn is over. One tool we can use to somehow
predict the turning points of a cycle is by analyzing cyclical
factors (CF) of the data. Estimated (July 1995 to December
2009) and forecasted (January 2010 to June 2010) cyclical
factors based on the decomposition model are presented in
figure 5. As we can see this CF time series does not show any
trend or seasonality. In other words, the only time-series
18. component shown is the cycle. According to this figure, it
seems that the new one-family housing market has passed the
trough of this cycle in 2008 and is recovering.Comment by
InformationServices: Analyze cyclical factors using

CONCLUSIONComment by InformationServices: Conclusion
What is the outlook for the housing market in the near future
and will this problem be over soon? In this paper, we focus on
new one-family houses sold in the U.S. Based on our forecast,
it seems that the worst of this market is over and it is on the
way to recovery.
