<p>Variable importance is measured as the reduction in predictive power by randomizing each variable, and the resulting variable importance scores are <i>z</i>-scores. Negative scores correspond to the proportional reduction in model performance as a result of variable randomization. Traits are ordered by importance to the predictive model, with the key predictive covariates in the upper left (e.g., litter size).</p>
