In this paper, we consider a proportional subdistribution hazards model in the presence of competing risks in case-cohort studies and examine a weighted estimating equation approach for parameter estimation.

WebFine and Gray proposed a proportional hazards regression model for the subdistribution of a competing risk with the assumption that the censoring distribution and the covariates are … Web26 Sep 2012 · Cause-specific hazard regression, subdistribution hazard regression, mixture models, vertical modelling and the analysis of time-to-event data based on pseudo-observations are described in this article and are applied to a dataset of a cohort study intended to establish risk stratification for cardiac death after myocardial infarction. Webwhere h is a known link function and X denotes covariates. This model extends the proportional hazards model (Fine & Gray, 1999) in that it allows covariates to have time-varying effects. Fine et al. (2004) consider a similar regression model, but in a more general framework with multiple states. outback call crossword
