Title: Recent Results on False Discovery Rate

Abstract: The concept of False Discovery Rate (FDR), which is the expected proportion of false positives (Type I errors) among rejected hypotheses, has been receiving increasing attention by researchers in multiple hypotheses testing. This talk will present some theoretical results on the FDR that have been recently developed in the context of stepwise multiple testing procedures. A comparison of various FDR-controlling procedures that exist in a given multiple testing situation will also be presented in terms of the expected proportion of false negatives (Type II errors) among accepted hypotheses.
