Re: st: Factor variables and outreg/outreg2

Dear all,
My aim is to obtain a table only for some coefficients (the
interaction terms or factor variables) using -outreg2-, but -outreg2-
does not work with factor variables. I found a thread where the same
problem was discussed on 28 January 2010, but there is no solution
provided.
Any suggestion/fix that could be implemented? Please find an example below.
Thanks
Mirko
