摘要
把随机效应的协方差推广为正定阵进行研究.首先给出混合效应模型中固定效应的最小二乘估计,然后用方差分析估计方法给出方差分量的估计.
Generalized the covariance of random effect to positive matrix in research. First presented least-squares estimation of fixed effect in mixed models,and then gave the estimation of variance components by method of variance analysis estimation.
