摘要
方差分量模型的随机效应的协方差为单位阵时《线性模型引论》已进行研究.把随机效应的协方差推广为正定阵进行研究.用最小范数二次无偏估计法给出方差分量的估计.
Variance component model of the random effects of covariance matrix unit for the "Linear model introduction" matrix has been studied. In this paper,the random effects of covariance matrix positive for the promo- tion of research. With minimum norm quadratic unbiased estimates of the variance components estimate is given.
