Hello @changxuosu ,
What do you mean by "testing on the Bayesian predictive model"?
Do you want to score new data with the Bayesian network?
Do you want to assess the quality of the Bayesian network (goodness-of-fit)?
Also, there's a special board for Data Mining questions :
Analytics > SAS Data Mining and Machine Learning.
The most appropriate board gives the quickest and most qualitative answers!
Cheers,
Koen
