Log-likelihood ratio χ was used to estimate improvement in global model fit.
88 To avoid model overspecification and compare among fitted models with k < 10 parameters, we assessed whether incorporating additional significant and non-significant terms resulted in global model improvement through likelihood ratio tests.
Our simulation study showed considerable improvements in global model fit when extreme residual heteroskedasticity was properly accounted for, though the advantage of heteroskedastic error WGP models seemed to dissipate quickly for even moderate amounts of environmental heterogeneity in residual variances, particularly under WGP models without variable selection (i.e., RR-BLUP and BayesA).
