Testing for the partial Koziol-Green model with covariates

Abstract

In this paper we consider some non-parametric goodness-of-fit statistics for testing the partial Koziol-Green regression model. In this model, the response at a given covariate value is subject to random right censoring by two independent censoring times. One of these censoring times is informative in the sense that its survival function is some power of the survival function of the response. The goodness-of-fit statistics are based on an underlying empirical process for which large sample theory is obtained. (C) 2002 Elsevier Science B.V. All rights reserved.
