Hi,3 questions before I may use the free trial:- How are categorical variables dealt with: can they be used as is or is a transformation necessary?- Is it possible to get a probability for the dependant variable( instead of a 0 / 1 )classification)- once a model is obtained can it be readily used on different (testing) data?sandoz
Please find my answers below:
1. You can use categorical variables for logistic regression without any transformation. If your dependent variables are ordered categorical then you should use the ordinal model. If these are unordered categorical variables then you should use the multinomial model.
2. The predicted probabilities are displayed in the output.
3. You can define a testing set through the dialog box in order to validate the model.
