Global explanations of Random Survival Forests (RSF). A RSF feature importance (VIMP). B Permutation importance (mean value and boxplots). C SHAP importance (mean |SHAP| value and SHAP value as beeswarm plot). D Rank-Biased Overlap (RBO) curves of variable rankings comparison for increasing values of depth d (number of important features considered) between RSF feature importance and mean permutation importance (in brown), RSF feature importance and mean |SHAP| importance (in gray), mean permutation importance and mean |SHAP| importance (in pink)
