st: saving regression coefficients

["Raphael Fraser" <raphael.fraser@gmail.com>]

I would like to run a two-stage analysis. The first of which saves the
following regression coefficients in one data set:

bysort id: regress chol year

I had in mind using a -forvalues- and -postfile-. id ranges from
1-200. i am not sure how to post the 1 x 2 regression coefficient
matrix.
