CE_22C Analysis of Clinical Trials: Theory and Applications
INSTRUCTOR(S): Devan Mehrotra, Alex Dmitrienko, and Jeff Maca

The course covers six important topics that commonly face statisticians and research scientists conducting clinical research: analysis of stratified trials, analysis of longitudinal data with dropouts, analysis of pharmacogenetics data, crossover trials, multiple comparisons, and interim decision making and adaptive designs.

The course offers a well-balanced mix of theory and applications. It presents practical advice from experts and discusses regulatory considerations. The discussed statistical methods will be implemented using SAS and R software. Clinical trial examples will be used to illustrate the statistical methods.

The course is designed for statisticians working in the pharmaceutical or biotechnology industries as well as contract research organizations. It is equally beneficial to statisticians working in institutions that deliver health care and government branches that conduct health-care related research. The attendees are required to have basic knowledge of clinical trials. Familiarity with drug development is highly desirable, but not necessary.

This course was taught at JSM 2005-2016 and received the Excellence in Continuing Education Award in 2005.

CE_23C Construction of Weights in Surveys
INSTRUCTOR(S): David Haziza

Most surveys are designed to provide statistics for a possibly (very) large number of characteristics of interest. Typically, the data collected are stored in a rectangular data file, each row corresponding to a sample unit and each column corresponding to a characteristic of interest. Made available on the data file is a weighting system. The idea is to construct a single weighting system applicable to all the characteristics of interest. The typical weighting process involves three major stages. At the first stage, each unit is assigned a base weight, defined as the inverse of its inclusion probability. The base weights are then modified to account for unit nonresponse. At the last stage, the weights adjusted for nonresponse are further modified to ensure consistency between survey estimates and known population totals. When needed, the weights undergo a last modification through weight trimming or weight smoothing methods in order to improve the efficiency of survey estimates. The goal of the course is to provide a detailed description of each stage. Participants should have a background in survey sampling and regression analysis. The course is intended to survey statisticians working in survey organizations, graduate students and users of survey data.

CE_24C Analysis of Categorical Data
INSTRUCTOR(S): Christopher Bilder and Thomas Loughin

We live in a categorical world! From a positive or negative disease diagnosis to choosing all items that apply in a survey, outcomes are frequently organized into categories so that people can make sense of them. In this course, participants will learn how to analyze the most common types of categorical data. The course is divided into four main sections. The first three sections are organized by response type: 1) binary/binomial, 2) multicategory, and 3) count. Within each section, we examine how to estimate and interpret appropriate models while giving practical advice on their use. The fourth section applies model selection and evaluation methods to those models discussed in the first three. The ideal background for participants is experience with multiple linear regression and with the application of likelihood-based methods (e.g., likelihood ratio). All computations will be performed using R, so familiarity with its basics is recommended. Participants who will benefit the most are those who do not have experience with categorical methods and those who already have experience but have not used them in R. In addition to handouts and R programs to perform every computation, a recording of the course will be available to participants after JSM.

CE_25C High-Dimensional Covariance Estimation and Portfolio Selection
INSTRUCTOR(S): Mohsen Pourahmadi

The course provides a broad introduction to covariance estimation for high-dimensional data and its role in portfolio selection in finance. It is known that in high dimensions the sample covariance matrix is a notoriously bad estimator of its population counterpart. We discuss the details for two useful and viable alternatives to the sample covariance matrix: First, the class of shrinkage estimators, which makes minimal structural assumptions on the population covariance matrix, shrinks the sample eigenvalues toward a central value. It includes the well-conditioned Ledoit-Wolf estimator and is pretty much in the spirit of the ridge regression. The second class is centered around factor models and principal component analysis (PCA) and makes hard to verify structural assumptions. Various case studies and data sets will be discussed in detail using some existing packages in R.

ML19 Pursuing a Career in Statistics and Statistical Programming - a Students' Perspective
SPONSOR: Section for Statistical Programmers and Analysts

SPEAKER(S): Jessica Colson

We may or may not realize statistics is a part of our everyday life. From sports data to wellness and environment, several fields rely on gathering and interpreting the data by simple or sophisticated statistical analysis to convert the data into meaningful information for further decision making. Because of this, the demand for statisticians, statistical programmers, and data analysts has been growing and would continue to grow future. The key question remains on how does one decide to consider and pursue a career in these fields? For those of us who are already in this field or someone like me who has started pursuing this career track, what are our responsibilities to encourage others to consider and pursue these careers as it will take lot more that what is being done via digital media etc.? This round table will be a great opportunity to hear others at the table with their specific thoughts and experiences that that want to share as individuals or based on their roles including (but not limited to) ASA or other sponsored activities.

TL06 Advances and Challenges in Disease Surveillance
SPONSOR: Section on Statistics in Defense and National Security

SPEAKER(S): Ronald Fricker, Virginia Tech

Throughout history, the human race has periodically been ravaged by disease. One of the most extreme examples is the Bubonic or Black Death plague pandemic of the 12th century that originated in Central Asia and by some estimates killed 60% of Europe's population. Seeking to avoid pandemics, where the threat of bioterrorism today makes timely and effective disease surveillance as much a national security priority as a public health priority, public health agencies conduct disease surveillance by actively gathering and analyzing human health and disease data. The two main aspects of disease surveillance are (1) early event detection, and (2) situational awareness, and statistical methods have played and continue to play an important role in both. In this roundtable, we will discuss recent advances in statistical methods for disease surveillance as well as the ongoing research and implementation challenges.

TL25 Best Practices in Predicting Customer Attrition
SPONSOR: Section on Statistics in Marketing

SPEAKER(S): Adraine Upshaw, BBVA Compass

Customer acquisition is a major focus of marketing departments in any organization. Customer attrition or churn should receive the same focus. In 2014, the Harvard Business review reported that acquiring a new customer is more than 5X the cost of retaining an existing customer. In the era of globalization, profit margins are shrinking in all industries. Data mining techniques can used to achieve the goal of retaining profitable customers. In the roundtable we will discuss various approaches in predicting customer churn.
