Permutation importance with grouping of correlated features. Displays permutation importance (right upper panel) and the drop-feature importance (right lower panel). Results are reported by taking the average across 2000 repetitions. The importance score (x-axis) is illustrated by the F1-score in the graphs, whereas the complete model evaluation table (accuracy, recall, precision, and F1 scores) is superimposed. Due to multicollinearity, illustrated in the correlation matrix (left panel), RAVLT subscores (Im, Delay and Recog) were grouped: RAVLT, and also for the two parts, A and B, of the TMT in the presented permutation results (right upper and lower panels)
