    @mdntth I've used the Generate Attributes operator to perform calculations like Absolute Error and such, You could try that.

    You can also use Set Role to specify one attribute as the prediction and the other as the label, and then just use any Performance operator after that.  The performance operators don't require a model, just a way to compare the prediction to the actual.
