| 摘 要： | 最近可加危险(AH)模型被广泛地应用于生存分析数据,模型的协变量可以假设为时间独立或时间相关的.基于混合治愈模型,有界累计危险治愈模型和"不正确"的比例危险模型.本文将上述的可乘危险模型延伸到可加的危险模型,这里的模型可以允许含治愈部分的生存数据的存在."不正确"的AH模型的识别和参数估计也将在本文给出讨论.

| Abstract: | Most recently,additive hazards(AH) models are extensively applied to analyze survival data,in which covariates are assumed to be time-independent or time-dependent.In this paper,we extend multiplicative hazards model which are based on mixture cure,no-mixture cure models and "improper" proportional hazards models to AH model which may accommodate survival data with long-term survivors.Identifiability of "improper" AH and its estimation are investigated in this paper. |
