My question is below:-
It is based on model performance model
When to use kolmogorov smirnov test, GINI, AUC? Help check the below
3.1 Applying CART I used rpart package to solved this
3.2 Interpret the CART model output <pruning, remarks on pruning, plot the pruned tree> rpart package too
3.3 Applying Random Forests I used randomForest package for this
3.4 Interpret the RF model output <with remarks, making it meaningful for everybody>
4.1 Confusion matrix interpretation- I used caret package
**
> 4.2 Interpretation of other Model Performance Measures <KS, AUC, GINI>
this is where I am having a problem. I don't understand What the question is saying and the application too. Should they be applied on test, train or predicted values
I mean the 4.2, about KS, AUC, GINI
