Speaker: Professor Rand Wilcox, University of Southern California

Talk Title: HOW MANY DISCOVERIES ARE LOST BY IGNORING MODERN STATISTICAL METHODS? AN UPDATE WHEN COMPARING GROUPS AND STUDYING ASSOCIATIONS

Talk Abstract: The goal is to summarize some recent results when comparing groups and dealing with regression.  The primary focus will be on results related to measuring effect size and comparing measures of association. Methods based on both Pearson’s correlation and robust measures of association will be described. The results on robust measures of association include situations where the strength of an association is based on a nonparametric regression estimator (LOESS) that provides a flexible approach to curvature. Other topics that will be briefly  discussed include an extension of the shift function to a two-way design, results related to testing the fit of a particular quantile regression estimator, and a new approach to ANCOVA.
