How to interprete the output of GBM for Survival analysis? #51

Open fritshermans opened 6 years ago

fritshermans commented 6 years ago

I'm interested in getting predictions expressed in expected lifetimes, survival curves etc. Could one please explain me what the output of predict.gbm is? Are these probably (log) partial hazards? Your help is much appreciated.

Yes, these are just like the predictions that would come out of coxph().
