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 ?
