Hello Ada,
Why don't you use the estimates store + estout combo? You could use it to
store the p-values of the coefficients. You could then export the stored
p-values, to a comma or tab delimited txt file, and latter import it back to
Stata.
Cheers,
JP

after estimation?
Thanks for the suggestion. I'm looping the estimation through
different samples, so often quite a (big) bunch of the variables got
dropped. I'll need to think of a way to drop the variables or the
zeros from the matrices.
Cheers,
Ada
