摘要: 利用正态总体的性质, 证明了当二维正态总体的均值满足一个或两个线性不等式约束时, 其线性函数的最大似然估计在Pitman准则意义下优于无约 束时线性函数的最大似然估计.

关键词: Pitman准则, 有约束的最大似然估计, 投影

Abstract: It is proved by means of the properties of normal populations that the restricted Maximum Likelihood Estimates (MLE) of linear function of the mean under the Pitman criterion is more optimal than the maximum likeliho od estimates of the linear function of the mean without restrictions if the mean of two-dimensional normal population satisfies one or two linear inequalit y restrictions.

Key words: Pitman criterion, restricted maximum likelihood estimates, projection
