线性指数分布模型的一类贝叶斯判别分析

Analysis of a Bayesian discriminate with linear exponential distribution model

设有两个总体Π0和Π1,分别服从参数为0θ和1θ的线性指数分布,对于待观测的寿命样本X,给出相应的判别分析问题的Bayes停止判决法则,其中损失函数包括试验费用和误判损失两部分.

Let Π0 and Π1 be two population sharing a linear exponential distribution with parameters θ0 and θ1,respectively.For the life sample X in an experiment,a Bayesian rule of discrimination cut-off was given for the corresponding discrimination analysis problem,where the loss function of the model was the sum of the experimental cost and the loss due to misjudgement.
