Change the program to: program foo2, eclass tempname bmat matrix `bmat' = e(b) matrix b = e(b) ereturn post b matrix `bmat'[1,1] = 122 ereturn repost b = `bmat' end This seems to work for both -regress- and -logit- Scott > -----Original Message----- > From: [email protected] [mailto:owner- > [email protected]] On Behalf Of Kirsten P Smith > Sent: Thursday, July 21, 2005 4:56 PM > To: [email protected] > Subject: st: Changing beta coefficients - w/ logistic regression > > Back in April, someone posted a question about how to change beta > coefficients. > > The answer given (more specifically, the sample code) works perfectly > for linear regression output.
