calibration plots for the five gradient boosting machine models using EPDS/GAD/PRES predictors. The validation set was partitioned into ten groups based on predicted risk. Each dot represents one of the ten groups. The mean risk within the group is plotted against the observed risk. If the dot falls on the diagonal line, then the predicted risk on average matches the observed risk, indicating excellent calibration. The shaded region is the confidence interval
