final approval

Let G_0 and G_1 be two populations having logarithmic normal distribution with parameters(μ_0,σ) and(μ_1,σ) for the life data in an experiment,the Bayesian methods of the classification problem are given in this paper according to the rule of minimum posterior risk,and a new rule is provided for the life classification.

基于寿命数据X、最小后验风险准则,给出了相应的判别分析问题的Bayes判别方法,为寿命判别制定了一个操作简便的规则。

μ=μ_1(μ_1>μ_0>0) are given in this paper according to the rule of minimum posterior risk,and a new rule is provided for the life classification.

本文依据最小后验风险准则,给出了上述问题的Bayes判决方法,为寿命判别制定了一个简便操作的规则。
