摘要
研究几何分布可靠度的先验分布分别为β分布和幂分布时,在熵损失函数下给出了可靠度的EB估计,并结合实际数据比较了两种先验分布下估计值的精度.
In this paper, the formula of Expect Bayes estimation of the reliability under entropy loss function for geometric distribution have been given, when the prior distribution of the reliability is power distribution and βdistribution. Example are also given to show the presition of the two prior distribution.
