st: Adding t-test (test difference from zero, not between two groups) to estpost

[Fabio Motoki <fmotoki@fucape.br>]

Hi there! I have run several regressions with statsby, and I need to
present summary statistics on the coefficients. Particularly, I want
to test whether the mean of the coefficients is statistically
different from zero. Using estpost summarize there is no option for
that. Any suggestions? The other stats I need (mean, median,
percentiles, count) I get from estpost summarize.

Cheers,

   Fabio
