摘要: 通过证明矩阵X, X′X及其子矩阵的一个关系 式, 得到了多元正态线性模型(Y,Xβ,σ2In)中参 数β的假设检验问题的检验统计量.

关键词: 正定矩阵, 子矩阵, 多元正态线性模型, 假设检验

Abstract: An equality is proved by discussing the relationship between a matrix and its submatrix and a test statistical variable for the parameter hypothesis test of liner model (Y,Xβ,σ2In) is obtained.

Key words: normal matrix, submatrix, multiple normal liner model, hypothesis test
