Variable Selection for Multivariate Survival data
It is assumed for the Cox’s proportional hazards model that the survival times of subjects are independent. This assumption might be violated in some situations, in which the collected data are correlated. The well-known Cox model is not valid in this situation because independence assumption among individuals is violated. For this purpose Cox’s proportional hazard model is extent to the analysis of multivariate failure time data, which includes frailty models and marginal model. In this paper frailty and marginal hazard models are discussed using nonconcave penalized likelihood approach. Detailed illustrations are also provided.
