- Δ(-2logL) : restricted likelihood ratio test = -2logLintercept_model + 2logLreaction_norm_model. are the variances of the residuals for MY and ADG, of the additive genetic effect of the dam on MY, of the additive genetic effects of the lamb on the intercept and slope of the linear reaction norms, respectively. ρi ‒ s, ρi ‒ v, ρs ‒ v are the correlations between intercept and slope, intercept and maternal effects, slope and maternal effects. β is the regression coefficient.
