If you fit a model in PROC PROBIT using any of the options LOG, LOG10, C=, or OPTC, and save the model using the STORE statement, then incorrect statistics are produced by the SCORE statement when PROC PLM is used to score a data set using the saved model. To avoid the problem, use the OUTPUT statement in PROC PROBIT to score new data. To do this, augment the data set used to fit (train) the model with the additional data to be scored as described in this note on scoring.

Beginning in SAS 9.4 TS1M3, the STORE statement is ignored when any of these options are specified.
