方差分量的谱分解估计

Spectral Decomposition Estimate of Variance Components

就线性混合模型中含有两个方差分量的情形,对方差分量的方差分析估计和谱分解估计进行比较,得到它们相等的充要条件,由此推出谱分解估计的优良性.

We compare the spectral decomposition estimate by the analysis of variance estimate in the linear mixed model with two variance components.The necessary and sufficient conditions are given for these two estimates to be equal.Thus the optimality of spectral decomposition estimate is deduced.
