| 摘 要： | 本文在几何分布的先验分布为幂分布时研究了其在熵损失函数下,可靠度的多层Bayes估计及其容许性,给出了可靠度的多层Bayes估计的计算公式.通过实例验证,在熵损失函数下计算出的几何分布可靠度的多层Bayes估计是稳健的,并进一步表明在熵损失函数下计算出的几何分布可靠度的多层Bayes估计值比其在平方损失函数下算出的结果精度更高.

| Abstract: | In this paper, the formula of Expect Bayes estimation of the reliability under entropy loss function and square loss function for geometric distribution have been given, when the prior distribution of the reliability is power distribution. The example are also given to show that the two Expect Bayes estimation formula are both steady and the precision of Expect Bayes estimation of the reliability for geometric distribution under the entropy loss function is higher than that of the square loss function. |
