Hello all, The next MaPSS talk of this semester will be at 17:00 on Mon 22nd October in Carslaw 535. It’s a great opportunity to meet fellow postgrads, listen to an interesting talk, and of course get free food! ************************************************************************************** Speaker: Kristen Emery Title: An introduction to FDR control and its application in Target-Decoy Competition Abstract: In the field of multiple hypothesis testing the most pressing problem is the need to control the overall error present in our conclusions without sacrificing the ability to obtain them. In this talk I will introduce FDR a widely used contemporary method of error control. I will attempt to provide the background and motivation of this methodology in a way that requires little background knowledge of statistics and testing procedures. I will then explore a single application of FDR control in a testing situation where traditional methods cannot apply. We will investigate Target-Decoy Competition a specialized method for testing without p-values and examine how it is able to control the FDR in this non-standard testing problem. Finally I will extend beyond the current framework for Target-Decoy Competition and use this extension to show an interesting link with the traditional testing methods we will examine in the first half. ************************************************************************************** See you there!
