摘要
本文根据《多元分析》的基本理论,推导在多元正态总体的协方差阵未知情况下,当 p=2k 时,对总体均值假设的一种检验方法,并应用这种方法解决实际中提出的问题。
This paper,based on the basic theory of the multivariate analysis, itnroduees a testing method to hypothesize the population mean under the eonditon of the unknown covarianee matrix ∑ of the multivariate normal population when 2k is equalled by P.Then the method is used to solve the practical problems.
