Overlay of the RMSE boxplots obtained during the two procedures (repeated cross-validation and repeated holdout evaluation) in order to better observe the differences in performance, if any. For each set, results are represented through a density wave with a boxplot below it, and the diamonds represent outlier results. Find in green the performance of cross-validation models and in orange repeated holdout evaluation models. The average performance on each set is close between each approach (difference less than 0.01), but the repeated hold-out evaluation approach has more dispersed results. Similar plots for R² are available in Supplementary Figure S29 and for MAE in Supplementary Figure S30.
