摘　　要：对一般的线性混合模型,研究其固定效应与随机效应线性组合的两步预测问题,给出了两步预测均方误差的一个近似计算公式,为比较不同方差分量估计的优劣性进一步奠定了基础.As far as the general mixed-linear model is concerned, this paper explores the two-staged prediction of the linear combination about the fixed effects, and the random effects and meanwhile an approximate computation formula is derived for the mean square error of the two-staged prediction which paves the way for comparing and contrasting the advantages and disadvantages of different variance components.
