BAYESIAN COMPARISON OF RANDOM REGRESSION MODELS FOR TEST-DAY YIELDS IN DAIRY CATTLE

Abstract

Several approaches can be used to compare models. The simplest method evaluates the overall goodness of fit of the model using residual variance estimates. The weakness of this approach is that it does not take into account the level of parameterization of the model. Deviance Information Criterion (DIC) (Spiegelhalter et al., 1988) is an asymptotic criterion that reflects
