Yes, you are correct. The model too complicated and I don't have idea which variables interact with the others. After use the code as you provided,I have 86 estimate value included the intercept but the predictors or variables are just 26 only. Btw, Thank you for your advice. Really appreciate that.
So far I will follow this to track the model. Its maybe take a lot of time because its hard to read the LOGISMOD file (file created from OUTMODEL= option). Thank you for the suggestion.
