From: Philippe on 22 May 2010 05:02 Hi all, I would like to add constraints in a proc logistic. Example: proc logistic data=myfile descending ; model y= x1 x2 x3 x3 x4 x5 x6 x7 x8 x9 x10 /selection=stepwise; run; and I would like to add a condition saying that in the final model, only parameters having a positive estimate would be included. How can I do that ? Philippe
