Using a CHAID model on a flag target, enabling boosting to enhance model accuracy (while all other parameters are set to their defaults) results in the following execution error: "Warning: Error: Field $R1-Target has an incorrect storage type in the data model."
Model runs fine without boosting and $R1-Target seems like an internally calculated field ... so I don't understand what's going on.
I raised an issue with Technical Support. Turns out it is a bug when CHAID is used from auto-classifier. There is an interim fix.
I'm running Modeler 17 with Fix Pack 1 (i.e. 18.104.22.168) and the link I was sent for applying IF020 is
This does not look like an error or warning that I have seen before and I think that you are correct in your suspicion that the
$R1-Targetis an internally calculated field; probably related to the first of the component models estimated as a part of the boosting.
I would suggest that you contact our Technical Support to open a PMR for them to investigate this error.
