线性指数危险率模型的贝叶斯判别分析

Bayesian Procedure in Classification Problem With Linear Exponential Hazard Function

设有两个总体Π0 和Π1 ,其危险率为具有不同参数的线性函数 .对于待观测的寿命样本X,给出了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 Π 0 and Π 1 be two populations, the hazard functions of which are linear exponential functions with different parameters.For the life data X in an experiment, the Bayesian stopping rule and decision rule of the classification problem are given in this paper, where the loss function of the model is the sum of the cost of the experiment time and the loss due to the wrong decision.
