Model Score Port

When you check the Score input data field on the Basic Options tab, this tells Logistic Regression to calculate predicted values when creating the model, which in turn adds the Predicted_Value, Probability_of_class_A, and Probability_of_class_B columns for that score in the output data. You can attach any kind of sink to this port: a Write to File stage, a Write to Null stage, and so on.
