Fig. 3.

Time-dependent AUC analysis. The plots compare the performance of the proposed tree-ensemble methods with their multivariable linear versions, as applied to the brain tumor data. Dots represent the medians across splits of training/test sets; lines depict the interquartile limits. Left plot: CPH (dashed lines) and CPH-TREE (solid lines); center plot: Weibull (dashed) and WEI-TREE (solid); right plot: AFT (dashed) and AFT-TREE (solid). High-resolution version of this figure can be viewed in the supplementary materials.
