Hi Alice, Miguel, I bumped into the same problem. If I understand the original question correctly, Alice, you were initially using the data source Decisions, not the "Decisions node" like Miguel answer implies? I'm asking because at least I'm using the data source Decisions to set the priors (i have a oversampled rare case data set directly as a data source, and I have computed the adjusted prior probabilities from the original data set outside the Miner), because SAS EMiner Documentation (for 12.1) specifically states that after this priors are then automatically used to compute the posterior probabilities in the models, and that should be all that is needed. But I have the same situation with scoring: apparently priors are not used in the scoring code. I wonder is this a bug in SAS code or in the SAS documentation? Also I do not completely understand Miguel's answer: if the priors are the problem here, and the SAS does not utilize the adjusted priors in Scoring, why not change the priors in the Decision node after modeling instead of Decision weights? Any help is appreciated... Cheers, Janne
