Hello ManOfHonor-
The Interactive Grouping node property Allow Out-of-Range Values is set to No by default. Here is information from the tooltip.
Allow Out-of-Range Values
Specifies whether values outside of the user-specified minimum and maximum values for scaling are allowed. When the Weighting Method is selected for the Binary Transformation, scaled values greater than 1 are set to 1 and values less than 0 are set to 0 for creating the Frequency variable.
For details about how to proceed, from within Enterprise Miner select Help -> Contents -> SAS Credit Scoring -> Interactive Grouping Node -> Interactive Grouping Node Train Properties: Interval Target Options. That section tells about various properties that you can set, depending on what you decide is appropriate for your analysis.
Have a great day!
