定数截尾缺失数据下双参数指数分布的近似Bayes推断

Approximation Bayesian Inference for Two-parameter Exponential Distribution under Multiply Type-Ⅱ Censoring

当寿命分布为双参数指数分布时,本文给出了定数截尾寿命试验数据缺失场合下参数的Bayes估计.为了计算上的方便,本文还给出了Bayes估计的一种近似计算方法.通过大量的Monte-Carlo数值模拟试验,表明这种方法是可行的.

When product life time follows two-parameter exponential disribution, this article provide a Bayesian estimator for the parameter under multiply type-Ⅱ censoring. In order to computer simply, an approximate Bayesian estimator is derived. By the Mante-Carlo simulation,we show the feasibility of this method.
