摘要
基于Mlinex损失函数,在逐步增加Ⅱ型截尾样本下,讨论Weibull分布参数的Bayes估计.取逆伽玛分布为共轭先验分布,给出参数的Bayes估计,证明估计的可容许性.通过数值模拟,说明Mlinex损失函数下估计的稳健性.
In this paper,we investigate a parameter Bayes estimation based on Weibull distribution under TypeⅡprogressively censored samples.To estimate the unknown parameters,the Mlinex loss function and the inverse gamma distribution are introduced.And then we proved the admissibility under the Mlinex loss function.Finally,by using Monte Carlo simulation,we show the feasibility of this method.
