摘要
本文讨论了具有部分缺失数据时两个Weibull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.
The present paper deals with the asymptotic properties estimation and likelihood ratio test for two Weibull Populations with partially missing data. The limit distributions of estimators and likelihood ratio test are given, the strong consistency of estimators is also proved.
