摘要
从应用角度出发,解决了双样本均值向量和协方差矩阵的检验问题.主要构造了协方差矩阵检验统计量的分位数表;拓宽了检验均值向量的统计量T2 的使用条件.
The testing problem of double sample’s average vector and covariance matrix has been solved in the paper. The distribution table of covariance matrix’s testing quantities is compiled; the condition for the application of T2 for testing the average vector is less strict.
