Multivariate regression is implemented in Stata with the command
-mvreg-. Questions like these (does Stata do ...) can usually be
answered by typing -findit ...-, in this case -findit multivariate
regression-
To quote from the reference manual (for Stata version 6, since I only
have the old manual at home): "The individual coefficients and standard
errors produced by -mvreg- are identical to those that would be
produced by -regress- estimating each equation separately. The
difference is that -mvreg-, being a joint estimator, also estimates the
between-equation covariances, so you can test coefficients across
equations and, in fact, the -test- syntax makes such tests more
convenient."
