矩阵的子矩阵与线性模型的假设检验

A Matrix' Submatrix and Hypothesis Test for Liner Model Parameter

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,X﹀,σ2 In)

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,σ 2I n) is obtained.
