Estimation of heterogeneous within-herd variance components using empirical Bayes methods: a simulation study.

Abstract excerpt

Genetic evaluation using BLUP can accommodate heterogeneous variances if the necessary variance components are known; this may require estimation of variance components within each heterogeneous subclass. Properties of sire and residual variance estimates obtained by an empirical Bayes approach,...
