Hi. I want to use marginsplot after FRM regression. I don't want to see all variables, but only one "meritocracy" which is additive index. Meritocracy variable take values from 0 to 5. Also, I want to see other dummies variables. If I calculate margins with "margins, dydx(*)", I have this problem:
-marginsplot, xdimension(meritocracy incent_red per_laureati exporter)
meritocracy not a dimension in margins results
r(322);
More, if I calculate margins only for "meritocracy", then I have this problem:
-margins meritocracy, dydx(*)
factor 'meritocracy' not found in list of covariates
r(322);

How can I resolve?
Thank you.
