摘要
在文献 [1 ]中提出的谱分解估计是一种在线性混合模型中同时估计固定效应和方差分量的新方法。在本文中 ,我们对带有两个方差分量的线性混合模型进行了谱分解估计和方差分析估计的比较。得出了方差分量的这两种估计在某些条件下方差相等 ,而且谱分解估计具有一些方差分析估计的最优性。
The spectral decomposition estimate(SDE)proposed by Wang and Yinis a new method of simultaneously estimating fixed effects and variance components in linear mixed models.In this paper,we compare the SDE with ANOVAE in the linear mixed models with two variance components.Our results show that these two estimates of variance components have equal variance under some conditions.Thus the SDE shares some optimalities of the ANOVAE.
