Statistical Methods for Analyzing Time-Dependent Events in Breast Cancer Chemoprevention Studies.

Abstract

The overall aim of our research proposal is the statistical investigation of a non-parametric estimate which we call redistribution-to-the-inside estimator (RTIE) for the survival function s(t) = Pr(X > t), where the survival time X is subject to interval censoring. Our research efforts in the first year have been focused on two aspects of RTIE for interval censored data satisfying the condition that for any pair f censoring intervals, either they are disjoint, or one is a subset of the other (DI condition). First, we have completed the implementation of a computer program oded in the C language to carry out the RTIE estimation procedure, including a Kaplan-Meier type plotting program for RTIE written in the S+ language. Second, we derive the uniform almost sure limit (strong consistency) of RTIE for any arbitrary S and any arbitrary censoring distribution function C under the DI model.
