Is there any way to manually set the positive class in the compare ROCs operator? It can be done in the Performance operator, but I can't find a way to do it  with Compare ROCs.

    there is no explicit mapping in the operator. You need to use Remap Binominals before, which allows you to set the positive class manually.

    I was looking at the tutuorial process. I do not see any warning when I change the positive and negative values to 'a' and 'b'. Am I doing something wrong?

    Hi,
    I think there shouldn't be any warning. You should be good. If you use Remap binominals you just need to be sure that your column is of type Binominal (not Nominal!) and that you include special attributes.
