Here is my guess:
The help file for -ereturn- states that -ereturn repost- is only
"allowed only after estimation commands that posted their results using
ereturn post." This got me thinking. A lot of the work done by -probit-
and -logit- isn't done in ado files. So it might be that some of the
results aren't posted throuh -ereturn post-. This hunge is supported by
the fact that the program works if you use -glm- to estimate the same
models:
*---------- begin example ---------
capture program drop tt
program define tt, eclass
ereturn repost b=c
end
sysuse auto, clear
glm foreign weight mpg trunk, family(binomial) link(probit)
matrix b=e(b)
matrix c=b*2
tt
*---------- end example -------------
Hope this helps,
Maarten
