Hi everyone,

Does anyone know how to use combomarginsplot with margins derived from the mimrgns command? For reference, I'm looking at the interaction between time and race in students' self-evaluations of their future grades. I'd like to combine plots that show what the addition of new controls does to the estimate of interest. I get as far as the "saving" option before Stata tells me my code is wrong. Any insight?

Code:
global controls age i.sex i.educ
mi estimate, or: svy: logistic pass i.race##i.year $controls
mimrgns i.race#i.year, predict(pr) cmdmargins post saving (f1, replace)
marginsplot, by(race) 

mi estimate, or: svy: logistic pass i.race##i.year $controls parent_educ
mimrgns i.race#i.year, predict(pr) cmdmargins post saving (f2, replace)
marginsplot, by(race) 

mi estimate, or: svy: logistic pass i.race##i.year $controls parent_educ zipcode
mimrgns i.race#i.year, predict(pr) cmdmargins post saving (f3, replace)
marginsplot, by(race)

Thanks for considering.
