| 摘 要： | 讨论了在协方差已知或未知情况下多维正态总体零均值假设检验的问题。首先利用降维法 ,将多维正态总体转化为一维正态总体 ,然后利用T 统计量或U 统计量来判断拒绝或接受原假设。

| Abstract: | This paper discusses the hypothesis test of multi|dimensional normal population with mean zero under the case whether the covariance matrix is known or not. First, the decreasing|dimension method is used to turn multi|dimensional normal population into one|dimensional normal population. Then either rejection of original hypothesis or acceptance of hypothesis is judged according to %T%|statistic and %U%|statistic. |

| Keywords: | multi|dimensional normal population hypothesis testing original hypothesis |
