CASE STUDY PATIENT DATA ETL (EXTRACT, TRANSFORM, LOAD) AND ANALYSIS PLATFORM ABOUT СLIENT Apex Global Solutions (Apex) is the premier provider of IT and financial services in the healthcare industry. Headquartered in NY, with offices in IL, MD, NJ and Israel, Apex has been servicing skilled nursing facilities and rehab centers nationwide, for over decade. EXECUTIVE SUMMARY With more than 300 nursing facilities Apex maintains all patient data in a large-scale data warehouse with hundreds of thousands of patient records being extracted from different source systems daily. In order to maintain this dataflow company required a solution to properly extract and normalize patients' data, detect discrepancies, duplicates and other issues. Challenges Since data for patients is often duplicated in multiple systems, solution should find corresponding records and properly attach them to a single master source. Data may have typos, or incorrect values in key identifiers – (social security number, DOB, HICN, etc.). Limited amount of time to download and transform large amount of data (gigabytes) on a daily basis. Mixture of source systems: different versions of SQL Server, FoxPro, custom APIs and CSV uploads in different formats. Data normalization to achieve field-level data consistency. I.e. same hospital or doctor may be spelled differently in different source systems. Solution Langate developed a custom solution to extract, transform and load (ETL) patient data into the data warehouse. Key deliverables: Scalable data processing workflows running on multiple servers in parallel. Automatic intelligent data analysis and matching algorithm tolerant of data variance. Configurable semi-automatic mapping engine for data normalization. Results The resulting solution producess point of reference patient information as a superset of data imported from different systems. All non-reconciled data mistakes and discrepancies are automatically reported to the responsible party. APEX was able to significantly reduce the amount of time spent on manually maintaining patients’ data. 545 8th Avenue, Suite 840 New York, NY 10018 888 526-4283 [email protected] www.langate.com.

Evolution of the Infographic
EVOLUTION OF THE INFOGRAPHIC: Then, now, and future-now. EVOLUTION People have been using images and data to tell stories for ages—long before the days of the Internet, smartphones, and Excel. In fact, the history of infographics pre-dates the web by more than 30,000 years with the earliest forms of these visuals being cave paintings that helped early humans find food, resources, and shelter. But as technology has advanced, so has our ability to tell meaningful stories. Here’s a look into the evolution of modern infographics—where they’ve been, how they’ve evolved, and where they’re headed. Then: Printed, static infographics The 20th Century introduced the infographic—a staple for how we communicate, visualize, and share information today. Early on, these print graphics married illustration and data to communicate information in a revolutionary way. ADVANTAGE Design elements enable people to quickly absorb information previously confined to long paragraphs of text. LIMITATION Static infographics didn’t allow for deeper dives into the data to explore granularities. Hoping to drill down for more detail or context? Tough luck—what you see is what you get. Source: http://www.wired.co.uk/news/archive/2012-01/16/painting- by-numbers-at-london-transport-museum INFOGRAPHICS THROUGH THE AGES DOMO 03 Now: Web-based, interactive infographics While the first wave of modern infographics made complex data more consumable, web-based, interactive infographics made data more explorable. These are everywhere today. ADVANTAGE Everyone looking to make data an asset, from executives to graphic designers, are now building interactive data stories that deliver additional context and value.

Monte Carlo Likelihood Inference for Missing Data Models
MONTE CARLO LIKELIHOOD INFERENCE FOR MISSING DATA MODELS By Yun Ju Sung and Charles J. Geyer University of Washington and University of Minnesota Abbreviated title: Monte Carlo Likelihood Asymptotics We describe a Monte Carlo method to approximate the maximum likeli- hood estimate (MLE), when there are missing data and the observed data likelihood is not available in closed form. This method uses simulated missing data that are independent and identically distributed and independent of the observed data. Our Monte Carlo approximation to the MLE is a consistent and asymptotically normal estimate of the minimizer ¤ of the Kullback- Leibler information, as both a Monte Carlo sample size and an observed data sample size go to in¯nity simultaneously. Plug-in estimates of the asymptotic variance are provided for constructing con¯dence regions for ¤. We give Logit-Normal generalized linear mixed model examples, calculated using an R package that we wrote. AMS 2000 subject classi¯cations. Primary 62F12; secondary 65C05. Key words and phrases. Asymptotic theory, Monte Carlo, maximum likelihood, generalized linear mixed model, empirical process, model misspeci¯cation 1 1. Introduction. Missing data (Little and Rubin, 2002) either arise naturally|data that might have been observed are missing|or are intentionally chosen|a model includes random variables that are not observable (called latent variables or random e®ects). A mixture of normals or a generalized linear mixed model (GLMM) is an example of the latter. In either case, a model is speci¯ed for the complete data (x; y), where x is missing and y is observed, by their joint den- sity f(x; y), also called the complete data likelihood (when considered as a function of ).

Questionnaire Analysis Using SPSS
Questionnaire design and analysing the data using SPSS page 1 Questionnaire design. For each decision you make when designing a questionnaire there is likely to be a list of points for and against just as there is for deciding on a questionnaire as the data gathering vehicle in the first place. Before designing the questionnaire the initial driver for its design has to be the research question, what are you trying to find out. After that is established you can address the issues of how best to do it. An early decision will be to choose the method that your survey will be administered by, i.e. how it will you inflict it on your subjects. There are typically two underlying methods for conducting your survey; self-administered and interviewer administered. A self-administered survey is more adaptable in some respects, it can be written e.g. a paper questionnaire or sent by mail, email, or conducted electronically on the internet. Surveys administered by an interviewer can be done in person or over the phone, with the interviewer recording results on paper or directly onto a PC. Deciding on which is the best for you will depend upon your question and the target population. For example, if questions are personal then self-administered surveys can be a good choice. Self-administered surveys reduce the chance of bias sneaking in via the interviewer but at the expense of having the interviewer available to explain the questions. The hints and tips below about questionnaire design draw heavily on two excellent resources.

Improving Critical Thinking Through Data Analysis*
Midwest Manufacturing Accounting Conference Improving Critical Thinking Through Data Analysis* Kurt Reding May 17, 2018 *This presentation is based on the article, “Improving Critical Thinking Through Data Analysis,” published in the June 2017 issue of Strategic Finance. Outline . Critical thinking . Diagnostic data analysis . Merging critical thinking with diagnostic data analysis 2 Critical Thinking . “Bosses Seek ‘Critical Thinking,’ but What Is That?” (emphasis added) “It’s one of those words—like diversity was, like big data is— where everyone talks about it but there are 50 different ways to define it,” says Dan Black, Americas director of recruiting at the accounting firm and consultancy EY. (emphasis added) “Critical thinking may be similar to U.S. Supreme Court Justice Porter Stewart’s famous threshold for obscenity: You know it when you see it,” says Jerry Houser, associate dean and director of career services at Williamette University in Salem, Ore. (emphasis added) http://www.wsj.com/articles/bosses-seek-critical-thinking-but-what-is-that-1413923730 3 Critical Thinking . Critical thinking is not… − Going-through-the-motions thinking. − Quick thinking. 4 Critical Thinking . Proposed definition: Critical thinking is a manner of thinking that employs curiosity, creativity, skepticism, analysis, and logic, where: − Curiosity means wanting to learn, − Creativity means viewing information from multiple perspectives, − Skepticism means maintaining a ‘trust but verify’ mindset; − Analysis means systematically examining and evaluating evidence, and − Logic means reaching well-founded conclusions. 5 Critical Thinking . Although some people are innately more curious, creative, and/or skeptical than others, everyone can exercise these personal attributes to some degree. Likewise, while some people are naturally better analytical and logical thinkers, everyone can improve these skills through practice, education, and training.

Theory and Applications of Monte Carlo Simulations
Theory and Applications of Monte Carlo Simulations Victor (Wai Kin) Chan (Ed.) InTech, 364 pp. ISBN: 978-953-51-1012-5 The book ‘Theory and Applications of Monte Carlo Simulations’ is an excellent reference for researchers interested in exploring the full potential of Monte Carlo Simulations (MCS). The book focuses on the latest advances and applications of (MCS). It presents eleven chapters that show to which extent sampling techniques can be exploited to solve complex problems or analyze complex systems in a variety of engineering and science topics. The book explores most of the issues and topics in MCS including goodness of fit, uncertainty evaluation, variance reduction, optimization, and statistical estimation. All these concepts are extensively discussed and examples of solutions are given in order to help both researchers and practitioners. Perhaps the most valuable parts of the book are the examples of ground- breaking applications of MCS in financial systems modeling and estimation of transition behavior of organic molecules, but every single chapter teaches at least one new application or explains a useful concept about MCS. The aim of this book is to combine knowledge of MCS from diverse fields to facilitate research and new applications of MCS. Any creative researcher will be able to take advantage of the presented techniques and can find plenty of applications in their scientific field. Monte Carlo Simulations Monte Carlo simulations are an extensive class of computational algorithms that rely on repeated random sampling to obtain numerical results. One runs simulations a large number of times over in order to obtain the distribution of an unknown probabilistic entity.
