Re: st: calculating a loglikelihood in regress

Dear all,
Does anyone know if it's possible to calculate a loglikelihood value
from regress? I tried to download and implement the command
"reglike", but I was unsuccessful. Perhaps someone is aware of an
up-to-date alternative, or can provide further instruction on how to
use the reglike procedure. Any insights would be much appreciated.
We could probably have a contest to see who can come up with the most
ways of doing this...If you've downloaded the programs from Stata's
ML book (see the book store) you can do
. mynormal price mpg rep78 foreign, nolog
My normal estimates Number of obs = 69
LR chi2(3) = 21.40
Log likelihood = -637.09633 Prob > chi2 = 0.0001
