WebThe proportional cause-specific hazards (CSHs) model and the proportional subdistribution (cumulative incidence function (CIF)) hazards model are widely used in competing risk analysis. In this paper, we prove that these two kinds of proportionalities cannot hold simultaneously for all CSH functions and all CIFs. Webcovariate e ects, a standard approach is to model the cause-speci c hazard func-tions of di erent failure types. Recently, Fine and Gray (1999) proposed directly modeling the subdistribution of a competing risk with a Cox type model. In this paper, we consider a more exible and general hazard model for the subdistribu-tion.

Web16 Apr 2012 · The subdistribution hazard can be thought of as the probability of failure due to cause k at a moment in time, given that no cause k failures have occurred thus far (with those who have failed from other causes considered among those still event-free with respect to cause k ).

WebThe proportional hazards model, proposed by Cox (1972), has been used primarily in medical testing analysis, to model the effect of secondary variables on survival. It is more like an acceleration model than a specific life distribution model, and its strength lies in its ability to model and test many inferences about survival without making ...
