Parametric accuracy estimates. Estimated prediction accuracies and model selection accuracies for CV2-style methods using the parametric method. (A) Solid curves: estimates of prediction accuracy. Dashed curves: true prediction accuracy based on $u_{n1}$. Dotted curves: estimated prediction accuracy using $y_{n1}$ from Figure 2A. Ribbons show $\pm 1.96\times SE$ over the 500 simulations. (B) Solid curves: Fraction of the 500 simulations in which the better method (between CV2 and single-trait) for predicting the true genetic values was correctly selected. Dotted curve: model selection based on the naive prediction accuracy.
