I found a funky work-around that does the trick for what I'm working on, but since I've gotten good answers from random questions here before on everything from drills to general solutions to a polynomial with non-integer exponents, I thought I'd ask:
If you do non-linear least squares in Stata for some reason it only seems to save all the information from the last parameter for you to return as a scalar. I don't have a lot of experience writing rclass type programs in Stata (I usually just do normal programming in a do file - none of the programming commands), though, so maybe it does store more than that. But when I hit "return list" it looks like it's just saving the last parameter.
Is that true? Why does it do that?
My work around is that I just rearranged the way that I wrote the non-linear equation so that each parameter gets it's turn as the last parameter. I return all the scalars and run through however many hundreds of simulations I need to. That does the trick. But obviously not all non-linear equations are amenable to that somewhat tedious work around, so I'm curious what you would do in normal situations.
