Inconsistency of ROC curves
Hello,
I generated a ROC curve for a logistic regression with a data set by using the performance operator, then clicking on criterion and AUC. Fine.
Then I used the same data set and use the Compare ROCs operator, picking logistic regression and decision tree as models. The ROC curves appear, and the ROC curve for the logistic regression is different from the one I obtained before! How can this be?
Best,
Bernardo
