In SAS^® 9.3 TS1M2, when an INMODEL= data set created under an earlier release of SAS is input to PROC LOGISTIC, the procedure terminates abnormally (zero divide, domain error, and so on.)

To circumvent the problem, the INMODEL= data set can be adjusted. For example, the following code assumes that the original model was a generalized logit model fit using the LINK=GLOGIT option.

   data one(type=logismod); 
     set score_model1;
     if (_TYPE_='L') then _MISC_=9;
     if (_TYPE_='X') then _MISC_=_MISC_+5;
     run;
   
   proc logistic inmodel=one;
     score data=model1 out=output_model1;
     run;

However, scoring using SAS 9.4 or later is recommended since the problem is fixed beginning in SAS 9.4.
