Generalized Log‐Rank Tests for Partly Interval‐Censored Failure Time Data

Abstract

Abstract In this paper, we consider incomplete survival data: partly interval‐censored failure time data where observed data include both exact and interval‐censored observations on the survival time of interest. We present a class of generalized log‐rank tests for this type of survival data and establish their asymptotic properties. The method is evaluated using simulation studies and illustrated by a set of real data from a diabetes study. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
