摘要
线性混合模型的未知参数分为两种,一种是固定效应,一种是方差分量对具有异方差的线性混合模型的固定效应和方差分量做谱分解估计,讨论它的有关统计性质·
Unknown parameter in linear mixed models, is divided into two classes, and one is fixed effects, the other is variance components. A s Pectral composition estimation, of the fixed effects and variance components in linear mixed models with heteroscedastic variances, is done and some corresponding statistic properties of the spectral decomposition estimation is discussed.
