Seems to me you are still looking for [sigma]_b[_cons]. Anyhow, Stata
(note: not STATA) will do out of sample estimation. You can save the
model without the data using -estimates save-. Others can open their
own dataset and than use -estimates use- to open your model, and than
they can use -predict- or whatever other post-estimation command they
want.

Hope this helps,
Maarten
