Effects of Collinearity on Cox Proportional Hazard Model with Time Dependent Coefficients: A Simulation Study

Journal of Biostatistics and Epidemiology, 2020
Background: The Cox proportional hazard model has gained ground in Biostatistics and other related fields. It has been extended to capture different scenarios, part of which are violation of the proportionality of the hazards, presence of time dependent ...

Partial orders with respect to continuous covariates and tests for the proportional hazards model [PDF]

, 2008
Several omnibus tests of the proportional hazards assumption have been proposed in the literature. In the two-sample case, tests have also been developed against ordered alternatives like monotone hazard ratio and monotone ratio of cumulative hazards ...
