st: Extracting the t-statistics from a regression output

[Dani Tilley <tilleydani@yahoo.com>]

Hi,

After I -regress y x1 x2 x3, noconstant- I need to access the vector of 
t-statistics for the null that beta_i=0. This corresponds to the third column on 
the regression output. I actually only need one of the t-stats but I don't think 
this simplifies the problem.
