Working with C&R Tree, have selected in model's Build Options; Objectives "Create a model for very large datasets" and in the Model tab have selected "Calculate raw propensity scores."
Once the model is built, do not see a $RP-response field; no propensity is generated.
Make change in Objectives, select Boosting or Bagging and then there is a $RP-response field.
Why is the model not creating a propensity field when created through the 'Create a model for very large datasets option'?
Resolving the problem
This problem has been reported to SPSS Development - Workaround Available
Use the prediction and the confidence to calcuate the raw propensity -- if prediction = 1 propensity = confidence, if prediction = 0 propensity - 1 - confidence.
