Copula Based Cox Proportional Hazards Models for Dependent Censoring
依赖删失下基于 Copula 的 Cox 比例风险模型
Most existing copula models for dependent censoring in the literature assume that the parameter defining the copula is known. However, prior knowledge on this dependence parameter is often unavailable. In this article we propose a novel model under which the copula parameter does not need to be known. The model is based on a parametric copula model for the relation between the survival time (T) and the censoring time (C), whereas the marginal distributions of T and C follow…
