Using Auxiliary Time-Dependent Covariates to Recover Information in Nonparametric Testing with Censored Data

Murray, Susan; Tsiatis, Anastasios A. - 2001

Murrayand Tsiatis (1996) described a weighted survival estimate thatincorporates prognostic time-dependent covariate informationto increase the efficiency of estimation. We propose a test statisticbased on the statistic of Pepe and Fleming (1989, 1991) thatincorporates these weighted survival...

Sequential Methods for Comparing Years of Life Saved in the Two-Sample Censored Data Problem

Murray, Susan; Tsiatis, Anastasios A. - 1999

This research develops nonparametric strategies for sequentially monitoring clinical trial data where detecting years of life saved is of interest. The recommended test statistic looks at integrated differences in survival estimates during the time frame of interest. In many practical...
