Hello, Has anyone used Proc Loess? I have been using it recently and have been getting vey impressive results. However I need to know what is the predictive formula that the Proc uses eventually to score a different dataset, something which I can use as follows.. Train the model on a data set in SAS and then use the resulting scoring formula and implement it in excel for example so that someone who does not have SAS can use the predictions? I shall really appreciate your help in this regard ... Many Thanks Abhishek
