Re: Antwort: Re: st: RE: matrix results saved

[Rodrigo Briceño <rjbriceno@gmail.com>]

Thanks Richard. Actually I tried with that option, but the thing is
that the results I want to save are in a matrix form, not in a scalar
form. So, when I used:

estat bgodfrey, lags(12)
scalar bg=r (chi2)
scalar pbg= r(p)

I got the type mismatch r(109) error.

Thanks.
