Cross-validation performance. Distribution of root mean square error (RMSE; (a)) and Pearson’s product–moment correlation (Pearson’s r; (b)) for out-of-sample predictions across repeated (20x) 10-fold cross-validations are visualized using boxplots. The mean and 95% CI are shown as a point and range in the center of each boxplot and represent the expected out-of-sample performance
