I'm surprised the original program doesn't work. Something to be aware of with Scott's solution: most of the ereturned stuff gets zapped once you run foo2. In particular, since e(predict) gets zapped, the p option on predict doesn't work. You can probably add lines to Scott's program to revive the ereturned stuff that gets lost but maybe there is a better way. The following shows what I am talking about: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
