| Abstract: | 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. |
