如果有两个成套的心理测验X和Y,分别由p和q个子测验组成,则它们之间的效度系数可以用ρ_(XY)=(1/r)sum from i=1 to r(λ_i)来度量,这里的λ_i是矩阵M=V_(YY)^+V_(YX)V_(XX)^+V_(XY)的第i个非零特征根。这样定义的广义的效度系数ρ_(XY)...如果有两个成套的心理测验X和Y,分别由p和q个子测验组成,则它们之间的效度系数可以用ρ_(XY)=(1/r)sum from i=1 to r(λ_i)来度量,这里的λ_i是矩阵M=V_(YY)^+V_(YX)V_(XX)^+V_(XY)的第i个非零特征根。这样定义的广义的效度系数ρ_(XY)在p=q=1或p=1,q>1时就是通常的心理测验中的效度系数。这个ρ_(TT)还可以作为一个成套测验T之信度系数的度量。文章给出了一个实例。展开更多
