Hi, Can anyone help me with the operator in Rapidminer to compare regression models like compare RoC for classification? Where in I can compare R square and test & train error. Also, any functionality/operator to treat high cardinality variable in Rapidminer. I googled it but couldnt find it. I can treat it manually by label encoding or frequency or  clustering. But I am looking for any operator. Regards,
