hello, I used xgboost model for prediction and check features importance. can I conclude that the more important explanatory variable according to feature-importance the more impact on target? As I know it doesn't.
Good question!
hello dears, I have just interested in IFRS9 ECL models. I have three question and I appreciate all answers. 1) which models are best for pd, LGD & EAD calculation when I have scarce (about...
