"Validation: Get classification performance AND costs"

Member Posts: 0 Newbie
Hi! I'm a RapidMiner newbie and I love the tool. I have a number of questions, but I'll limit this post to the one.
I'm trying to validate a cost sensitive classification method that I implemented. I would like to produce both a confusion matrix and misclassification costs based on applying the generated model to a test training set. Right now, I can only seem to produce one or the other by having either as the last step in an operator chain. Am I missing an easy way to produce both or do I need to implement my own operator that does this?
Any help is appreciated.

Do you know the IOMultiplier - Operator? Applying this to the test-set allows you to perform both PerformanceOperators in a row.
hope this what you need
