]]> Martingales versus Empirical Process Theory in Proving the Functional Central Limit Theorem for Repeated Logrank Statistics http://www-math.umd.edu/research/seminars.html Mon, 28 Mar 2016 15:00:00 EDT Where: MTH0201
Speaker: Eric Slud (UMCP) -
Abstract: In this talk, I will begin by defining the logrank statistic for testing equality of survival outcomes in a two-group survival experiment and briefly explain its relation to martingales. The Martingale Central Limit Theorem turns out to be a very good way to prove a Central Limit Theorem for this kind of statistic, when the data-sample is large. However, suppose one wishes to prove a Functional Central Limit Theorem covering the large-sample behavior of the logrank statistic calculated repeatedly over time, considered as a stochastic process. Then we will see that empirical process techniques and NOT martingales are the best way to prove a large-sample limit theorem.

The material of the lecture will intersect material from survival analysis (logrank statistic, which is discussed for example in the Survival Analysis text of Klein and Moeschberger), from a couple of well-known papers one by Tsiatis (1982), one by Sellke (1984) and one by me (1984), and from empirical-process material that can be found in later papers of Ming Gao Gu.
