By using the theory of the likelihood ratio test, a method for choosing prior distributions and classes of prior distribution is given. 摘要利用似然比检验原理，给出了选取先验分布及先验分布族的似然比检验方法。
The present paper deals with the asymptotic properties of estimation and likelihood ratio test for-two exponential populations with partially missing data. 摘要讨论部分缺失数据两指数总体的参数估计和关于总体相同的似然比检验。
