It is of interest in some applications to determine whether there is a relationship between a
hazard rate function (or a cumulative incidence function) and a mark variable which is only …

A primary endpoint of AIDS trials is the length of survival. Often there is auxiliary information
available on measures of disease progression, which significantly alter the risk of mortality …

We present nonparametric tests for the comparison of two mean residual life functions. We
propose a new graphical approach for the simultaneous comparison of two mean residual …

Current status data arise when the only knowledge about the failure time of interest is
whether the failure occurs before or after a random monitoring time. We propose to analyse …

For time-to-event data with finitely many competing risks, the proportional hazards model
has been a popular tool for relating the cause-specific outcomes to covariates (. The …

The efficacy of an HIV vaccine to prevent infection is likely to depend on the genetic variation
of the exposing virus. This paper addresses the problem of using data on the HIV sequences …

For the competing risk setting where the lifetime data are due to one of several distinct and
exclusive causes, comparison of cause-specific hazard rates is of interest to researchers. In …

Values for 0 are obtained by Newton-Raphson updating of az and, B for a fixed value of k
and then maximizing the log-modified-likelihood function over k. SUBROUTINE MODLIK …

Abstract The Nelson-Aalen estimator provides the basis for the ubiquitous Kaplan-Meier
estimator, and therefore is an essential tool for nonparametric survival analysis. This article …

The product limit method of Kaplan and Meier for estimating survival functions and the
logrank test of Mantel are widely employed for analysis of longitudinal medical data …
