The optimal cut-off value was 52.9 for PNI, corresponding to the maximum Youden index.

Witryna17 kwi 2024 · At each level, DTs look for the best possible split so that they optimize the corresponding splitting criteria. But DTs splitting algorithms can’t see far beyond the current level in which they are operating (they are “greedy”), which means that they look for a locally optimal and not a globally optimal at each step.
