Abstract

There is considerable amount of literature dealing with inference about the parameters in a heteroscedastic one-way random effects ANOVA model. In this paper we primarily address the problem of improved quadratic estimation of the random effect variance component. It turns out that such estimators with a smaller MSE compared to some standard unbiased quadratic estimators exist under quite general conditions. Improved estimators of the error variance components are also established
