摘要
针对随机截尾试验模型 ,导出了失效数据组的联合分布函数 ;在受试样本服从指数分布的条件下 ,获得了参数θ的极大似然估计及其性质 ,这是相对于定数截尾和定时截尾来说更具有一般意义的结果。
By using the model of randomly censored exponential life data,we have obtained the combined distributing function of invalidation data.At the same time,we have also obtained the LSE and its property about the parameter θ .The result is more meaningful than the censored models of fixed number or fixed time.
