Class of Nonparametric Procedures for Comparing Two Survival Distributions Overan Interval Based on Randomly Right Censored Data

摘要

A class of nonparametric tests for comparing two survival distributions F and Gbased on randomly right censored data is proposed. The tests developed assume neither the proportionality of the hazard functions of F and G nor the equality of the censoring distributions. A subclass of the proposed tests compares favorably to the Gehan and logrank tests for testing standard hypotheses. It can be used to test hypotheses concerning F and G over a prespecified interval.
