marginal effects in IVprobit model

[Ashish Chouhan]

Dear statalist members,
I am using Ivprobit model to address simultaneity in my regression model where adoption decision is my dependent variable (yes=1 and no=0).
After running the model ivprobit dep_var exo_vars (endog_var=Instr_var), vce(robust) and estimating the average marginal effects using "margins, dydx(*)", I am getting marginal effects same as my coefficients. Is my syntax correct? Any help in this regard is appreciated.
Thank you.

The default is the linear prediction. If you want to compute the average marginal effect of your variables on probability of a positive outcome:

margins, dydx(*) predict(pr)

Thank you. That helps a lot.
