Title: Improved estimation of variance components in mixed models
Abstract: Abstract Taking Albert's (1976) formulation of a mixed model ANOVA, we consider improved estimation of the variance components for balanced designs under squared error loss. Two approaches are presented. One extends the ideas of Stein (1964), The other is developed from the fact that variance components can be expressed as linear combinations of chi-square scale parameters. Encouraging simulation results are presented. Keywords: variance componentsANOVA decompositionbalanced designssquared error loss
