【摘要】 截断数据是生存分析的重要研究内容 ,而关于污染数据的分析在近几年也越来越受到人们的重视 .本文考虑的是二者的混合情形 ,对定数截断下的污染指数分布模型的有关性质进行讨论 ,并据此对定数截断指数分布模型下的有关数据处理方法作出修正 ,以求得到更加精确的统计分析结果更多还原

【Abstract】 Survival analysis attaches much importance to censored data,and the analysis of contaminated data is getting more and more notice in recent years.In this paper we consider the mixed situation of them,discuss some properties of the contaminated exponential distribution model with type Ⅱ censoring,and adjust the method of dealing with type Ⅱ censored data with exponential distribution in the life tests to reach more precise results.更多还原
