PROC LOGISTIC may take a long time to complete and the procedure or SAS may abnormally terminate if both of the following conditions are true:
The execution time increases with the number of combinations of the levels of the CLASS variables. When the number of combinations becomes sufficiently large, the procedure terminates abnormally issuing such error messages as Read Access Violation or other system-specific messages. SAS may also terminate.
Under the above conditions, PROC LOGISTIC does not produce the default effects plot as described in the LOGISTIC documentation. Instead of producing a plot of the predicted probability versus the first CLASS covariate with a line for each level of the second CLASS covariate, it attempts to plot the predicted probability versus all combinations of the CLASS variables.
To avoid this problem, specify effect suboptions to produce the desired plot. The default plot described in the LOGISTIC documentation is produced by specifying PLOTS=EFFECT(X=ClassVar1 SLICEBY=ClassVar2 JOIN=YES), where ClassVar1 and ClassVar2 are the first and second CLASS variables in the model respectively.
