Talk Title: Exploration, Confirmation and Replication in the Same Observational Study

Talk Abstract: Exploratory data analysis, confirmatory data analysis and replication are three important aspects of building strong evidence from observational studies. Exploratory data analysis, confirmatory data analysis and replication are often thought of as being done on separate studies. However, for settings where randomized experiments are impossible to conduct for ethical reasons and observational studies must be relied on, it is common that there is a data set with unique strengths. We develop a two-team cross screening approach that allows for exploratory data analysis, confirmatory data analysis and replication to be done in the same observational study data set. We apply the approach to study the effect of unwanted pregnancy on mothers' later life outcomes using data from the Wisconsin Longitudinal Study. We will also briefly discuss data turnover, a one team cross-screening approach that provides some of the benefits of two-team cross screening with only one team. This is joint work with Samrat Roy, Marina Bogomolov, Ruth Heller, Amy Claridge, Tishra Beeson and Will Bekerman.

Wijsman Lecture: Ming Yuan - Columbia University

Talk Title: : A cumulant approach to linear regression
Talk Abstract: Linear regression is a cornerstone of statistics. Despite its generality and flexibility, its interpretation can be subtle. In this talk I will describe a new perspective to linear regression through the lens of higher order cumulants and discuss how it offers new insights into a number of classical problems including the omitted variable bias.
