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. 证明估计的强相合性和渐近正态性, 给出似然比检验统计量的极限分布, 并讨论基于精确分布的检验问题.

关键词: 缺失数据, 极大似然估计, 似然比检验, 极限分布

Abstract: The present paper deals with the asymptotic properties of estimation and likelihood ratio test for-two exponential populations with pa rtially missing data. The limit distributions of estimators and likelihood ratio test are given, the strong consistency of estimators is also proved.

Key words: missing data, maximum likelihood estimation, test for likelihood-ratio, limit distribution
