摘要：

In this paper,the estimation of variance components in the linear mixed model with two random effects is investigated.The class of combination estimates based on the quadratic invariant statistics and consistent nonnegative estimates are obtained.Furthermore,it is shown that the consistent nonnegative estimate dominates ANOVA estimate under some conditions.
