This document outlines an analysis of health insurance rate data from Healthcare.gov to identify key factors that influence individual rates. The analysis included downloading nationwide data from Healthcare.gov, selecting Delaware data, cleaning the data, and performing various analyses including decision trees, partial least squares, and neural networks. The analysis found that age, insurance plan version number (whether a plan was marked up or down), and insurance issuer were the most significant factors in determining individual health insurance rates in Delaware.
Overcoming Big Data Bottlenecks in Healthcare - a Predictive Analytics Case S...Damo Consulting Inc.
Implementing population health management in transitional care settings is challenging because of: 1) Data interoperability and other bottlenecks 2) complex workflows designed for reactive rather than proactive processes; and 3) difficulty in integrating them into clinical workflows
This presenattion discusses t a use case demonstrating a practical, real-world solution to these challenges.
Three audience takeaways from presentation:
1. Learn about the big data bottlenecks in healthcare
2. Learn how Sutter Health is using its E.H.R. data in a readmission risk predictive model;
3. See how those predictive models are integrated into clinical operations in improving care
In this article, Jim Hoffman, COO of BESLER Consulting, discusses current uses of predictive analytics in healthcare. It was featured in the September 2014 edition of Managing Health Today, a publication of the Hudson Valley Chapter of HFMA.

Improving Healthcare Operations Using Process Data Mining Splunk
It’s estimated that 80% of healthcare data is unstructured, which makes it challenging to do any sort of analytics to drive improvements in population health, patient care and operational efficiency. Machine learning techniques can be utilized to predict future events from similar past events, anticipate resource capacity issues and proactively identify bottlenecks and patient outcome risks. This session will provide an overview of how process data mining can be applied to healthcare and provide real-world examples of process data mining in action.
How To Avoid The 3 Most Common Healthcare Analytics Pitfalls And Related Inef...Health Catalyst
Analytics are supposed to provide data-driven solutions, not additional healthcare analytics pitfalls and other related inefficiencies. Yet such issues are quite common. Becoming familiar with potential problems will help health systems avoid them in the future. The three common analytics pitfalls are point solutions, EHRs, and independent data marts located in many different databases. An EDW will counter all three of these problems. The two inefficiencies include report factories and flavor of the month projects. The solution that best overcomes these inefficiencies is a robust deployment system.
Optimize Your Healthcare Data Quality Investment: Three Ways to Accelerate Ti...Health Catalyst
Healthcare organizations increasingly rely on data to inform strategic decisions. This growing dependence makes ensuring data across the organization is fit for purpose more critical than ever. Decision-making challenges associated with pandemic-driven urgency, variety of data, and lack of resources have further highlighted the critical importance of healthcare data quality and prompted more focus and investment. However, many data quality initiatives are too narrow in focus and reactive in nature or take longer than expected to demonstrate value. This leaves organizations unprepared for future events, like COVID-19, that require a rapid enterprise-wide analytic response.
What are some actionable ways you can help your organization guard against the data quality challenges uncovered this past year and better prepare to respond in the future? Join Taylor Larsen, Director of Data Quality for Health Catalyst, to learn more.
What You’ll Learn
- How data profiling and data quality assessments, in combination with your data catalog, can increase data quality transparency, expedite root cause analysis, and close data quality monitoring gaps.
- How to leverage AI to reduce data quality monitoring configuration and maintenance time and improve accuracy.
- How defining data quality based on its measurable utility (i.e., data represents information that supports better decisions) can provide a scalable way to ensure data are fit for purpose and avoid cost outstripping return.

Application of data science in healthcareShreyaPai7
Data Science is a field that is widely applied in most other domains on a regular basis. The huge amount of data generated regularly calls for sophisticated methods of analysis so that the best interpretatiosn can be drawn from them. Healthcare is one such field in which data science is being used extensively.
With all the buzz around machine learning, predictive analytics, and artificial intelligence (AI) there are a lot of misconceptions and misunderstandings surrounding the optimal use of modern machine learning tools. Healthcare.ai, a free software package developed by the Health Catalyst data science team, was recently released to help hospitals gain valuable insights and advance outcomes improvements from their immense data sets. The software automates machine learning tasks and democratizes machine learning by making it accessible to ‘citizen data scientists’. We have received several questions about machine learning in healthcare, such as how do you define machine learning, how is it different than AI, what are some common uses cases for machine learning in healthcare, and what are the pitfalls. This webinar will develop a common vocabulary around these ideas. We’ll cover the differences between the most cutting-edge predictive techniques, how a model can be improved over time, and use case vignettes to understand and avoid typical machine learning pitfalls. In today’s healthcare industry, the fastest path to healthcare outcomes is often achieved using the simplest predictive tools.
Mike Mastanduno, PhD, data scientist, and Levi Thatcher, PhD, director of data science, will discuss the landscape of healthcare-specific machine learning. Mike and Levi have extensive experience building and deploying impactful machine learning models using healthcare.ai and have worked at the cutting edge of medical research. During and after the discussion, they will answer viewer-submitted questions. This webinar will:
Compare and contrast machine learning and AI.
Discuss techniques that offer feedback into the system and when it’s necessary to retrain a model.
Give advice on how to avoid common pitfalls in machine learning implementation.
Provide use case example and vignette examples on how to apply the different classes of machine learning techniques.

STAT 2103 Project 4 Performing a Multiple Linear Regress.docxdessiechisomjj4
STAT 2103 Project 4:
Performing a Multiple Linear Regression Analysis
Goal: Use the data set provided and the statistical methods learned in class to carry out an
applied multiple linear regression analysis.
Data: The data set for this project has been posted to Blackboard. The observational units in the
sample are 146 countries. The response variable (Y) is a “HAPPY”, an index of each country’s
overall happiness. Also included are 10 predictor variables (X’s), such as GDP, life expectancy,
health care expenditure, and population density. The “Description” tab explains each variable.
Method: You can complete the regression using StatCrunch (recommended) or Excel:
StatCrunch: On MyStatLab, select “StatCrunch”, then “StatCrunch website”, then “Type
or paste data into a blank data table”. Then use the “Stat” menu, “Regression”, and
“Multiple Linear”. Choose the correct variables and specifications.
Excel: Download “Analysis ToolPak” add-in (File – Options – Add-Ins – Manage). Then
“Data Analysis”, select “Regression”. Choose the correct input and specifications.
Assignment: Perform a multiple linear regression analysis. This includes:
List Variables: Select and list 4 predictor variables that you think may be related to
happiness.
Explore Variables: Include a scatterplot of the response variable “HAPPY” on the y-axis
and one of your predictor variables on the x-axis. Describe their relationship/correlation.
Write Model: Construct and write out a multiple linear regression model with your
selected variables.
Analyze Model: Use the statistical output to identify which predictor variables are
significantly important and how much of the variability in the response variable is
explained (the r
2
value).
Finalize Model: Rerun the regression model using only the significant predictor variables.
(If none were significant the first time, use the two variables with the lowest p-values.)
Learn from Model: Choose one variable from this finalized model and interpret its
coefficient. Also, why do you think that the r
2
is so high or so low?
Predict with Model: Select a country from the sample. Use the values of that country’s
predictor variables and the final regression model to estimate that country’s HAPPY
index. Find how much the model overestimated or underestimated the true value.
Details: Due date is in class on Thursday, December 4. The previous class on Tuesday,
December 2 will be partially spent as an in-class work day for the project, so it is recommended
that you bring your laptop to class that day if you have questions.

2016 data-science-salary-survey - O’Reilly Data ScienceAdam Rabinovitch
IN THIS FOURTH EDITION of the O’Reilly Data Science
Salary Survey, they analyzed input from 983 respondents
working in the data space, across a variety of industries—
representing 45 countries and 45 US states. Through the
results of our 64-question survey, we’ve explored which tools
data scientists, analysts, and engineers use, which tasks they
engage in, and of course—how much they make.
Key findings include:
• Python and Spark are among the tools that contribute
most to salary.
• Among those who code, the highest earners are the ones
who code the most.
• SQL, Excel, R and Python are the most commonly used
tools.
• Those who attend more meetings, earn more.
• Women make less than men, for doing the same thing.
• Country and US state GDP serves as a decent proxy for
geographic salary variation (not as a direct estimate, but
as an additional input for a model).
• The most salient division between tool and tasks usage
is between those who mostly use Excel, SQL, and a small
number of closed source tools—and those who use more
open source tools and spend more time coding.
• R is used across this division: even people who don’t code
much or use many open source tools, use R.
• A secondary division emerges among the coding half—
separating a younger, Python-heavy data scientist/analyst
group, from a more experienced data scientist/engineer
cohort that tends to use a high number of tools and earns
the highest salaries.

Computing Descriptive Statistics
Computing Descriptive Statistics: “Ever Wonder What Secrets They Hold?” The Mean, Mode, Median, Variability, and Standard Deviation
Introduction
Before gaining an appreciation for the value of descriptive statistics in behavioral science environments, one must first become familiar with the type of measurement data these statistical processes use. Knowing the types of measurement data will aid the decision maker in making sure that the chosen statistical method will, indeed, produce the results needed and expected. Using the wrong type of measurement data with a selected statistic tool will result in erroneous results, errors, and ineffective decision making.
Measurement, or numerical, data is divided into four types: nominal, ordinal, interval, and ratio. The businessperson, because of administering questionnaires, taking polls, conducting surveys, administering tests, and counting events, products, and a host of other numerical data instrumentations, garners all the numerical values associated with these four types.
Nominal Data
Nominal data is the simplest of all four forms of numerical data. The mathematical values are assigned to that which is being assessed simply by arbitrarily assigning numerical values to a characteristic, event, occasion, or phenomenon. For example, a human resources (HR) manager wishes to determine the differences in leadership styles between managers who are at different geographical regions. To compute the differences, the HR manager might assign the following values: 1 = West, 2 = Midwest, 3 = North, and so on. The numerical values are not descriptive of anything other than the location and are not indicative of quantity.
Ordinal Data
In terms of ordinal data, the variables contained within the measurement instrument are ranked in order of importance. For example, a product-marketing specialist might be interested in how a consumer group would respond to a new product. To garner the information, the questionnaire administered to a group of consumers would include questions scaled as follows: 1 = Not Likely, 2 = Somewhat Likely, 3 = Likely, 4 = More Than Likely, and 5 = Most Likely. This creates a scale rank order from Not Likely to Most Likely with respect to acceptance of the new consumer product.
Interval Data
Oftentimes, in addition to being ordered, the differences (or intervals) between two adjacent measurement values on a measurement scale are identical. For example, the di ...

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

1. HEALTH INSURANCE RATE ANALYSIS
AND PREDICTION
USING HEALTHCARE.GOV
MARKETPLACE DATA

2. The Health Insurance Marketplace Public Use Files
(PUF) which contain data on health and dental plans
offered to individuals and small businesses through
the US Health Insurance Marketplace.

3. PROJECT DIRECTIONS, PROCEDURES, GOALS:
• DOWNLOAD NATIONWIDE DATASETS FROM HEALTHCARE.GOV
• LOOK AT THE METADATA AND SEE IF IT MATCHES WITH YOUR PROJECT GOALS.
• IDENTIFY THE BEST SUITED DATASET FROM THE DOWNLOADED BUNCH OF INSURANCE
DATASETS
• CLEANUP THE DATA USING JMP TOOLS : ROWS, COLS MENU, DATA FILTER, ROW
SELECTION ETC.
• NARROW IT DOWN TO STATE OF DELAWARE DATA
• PRELIMINARY ANALYSIS OF THE DATA – MARK THE NECESSARY COLUMNS, DELETE EMPTY
COLUMNS
• CHECK FOR CONSISTENCY OF DATA USING GRAPH BUILDER
• CONVERT THE CATEGORICAL VARIABLES: AGE TO NUMERIC, RATE TO CURRENCY, REMOVE
$ SYMBOL
• FURTHER CORE ANALYSIS: DECISION TREE, PARTIAL LEAST SQUARES, NEURAL NETWORKS

4. I have selected the huge individual rates file out of the 18 downloaded
datasets. Selected DE data, Cleaned up age column, made it numeric,
cleaned up rate column by removing dollar sign, removed insignificant
columns like tobacco for DE, eliminated empty columns. Tools used are
data filter, row selection, formula editor etc.

5. THE DATA
Now the rate_puf.csv became rate_DE.jmp with all clean data
5
6. There is steady increase
of rate per month, year
There is steady increase
of rate with age
Finding out which Issuer
holds most Business in
State of DE
Which issuer have
marked up and down
versions of Plans
Have done various analysis, to make sure I am choosing the correct X
factors.. There is an interesting 3D plot with Rate as Y, Age and version
number as X and Z.

7. The first analysis is the Partition decision tree – I chose this because of
the significant number of categorical variables. The major report
elements are towards the right.
7
8. Here is a beautiful story unfolding – from the insurance rates of state of
Delaware, from Healthcae.gov – out of 15,928 individuals, 1350 people
of prime age have 0 premium. The Major contributors of the premium
are listed in the green rectangle. Age is the most decision factor – 14
splits. The second is the version number, which I believe is the marked
up or down version of the same plan, by healthcare.gov – 8 splits, then
the issuer – various companies that offer healthcare plans. The rest of
the components are insignificant. Altogether 25 splits on the above
mentioned prime components. Decision tree is the best choice when
many of the variables are categorical. And there is only one Y, which is
the rate per individual.

9. 3D TREE
The Rsquare looks good, Actual by Predicted Plot is symmetrical. 3 split
trials gave similar results

15. COMPARING PREDICTION PROFILERS :
PLS, DECISION TREE, NEURAL NETWORK
Out of curiosity, I compared the decision tree with another method –
partial least squares, which mostly support continuous variables. The
above mentioned prediction profiler sounds very interesting. Look at
the ways. Major factors in the rate prediction, in the state of Delaware
are 1. Age, (rate increases with age) Version numer (the higher the
number, lower the rate. Low version numbers have marked up
premium), then categorical variables such as issuerid1 and issuerid2
take up next places. We have 2014,15 and 16 data, there is constant
insignificant increase with month and year.

16. THE
BEGINNING...
LESSONS LEARNED, CONCLUSIONS, APPENDIX:
✓ START EARLY, MAKE EVERY EFFORT TO CLEAN DATA, ANALYZE AND RE-ANALYZE USING GRAPHS
✓ ELIMINATE UNWANTED DATA, GET OPTIMUM DATA FOR EVALUATION
➢ WHEN THERE ARE SIGNIFICANT CATEGORICAL VARIABLES, PARTITION DECISION TREE IS A GOOD
CHOICE.
➢ FIT MODEL->PLS ALSO ACCEPT A MIXTURE OF CATEGORICAL AND NUMERIC VARIABLES AND GIVES
OPTIMUM RESULTS.
➢ NEURAL NETWORKS WORKS WONDERS WITH LARGER CLEANER DATASETS.
➢ FROM ALL THE ANALYSIS, AGE, ISSUER, MARKED UP-DOWN VERSION NUMBER ARE THE MOST SIGNIFICANT
FACTORS IN DECIDING THE INDIVIDUAL RATE.
➢ FOR RATE PREDICTION, MAJOR COMPONENTS ARE:
➢ 1. AGE 2. VERSION NUMBER
➢ 3. ISSUERID, ISSUERID2 4. MONTH AND YEAR
