Dear Statalist Users,

I am hoping for some insight into the issue that I am facing.

I am using IVPROBIT command in stata and the coefficients of the regression are exactly same as that of the marginal effects.

https://www.stata.com/statalist/arch.../msg00405.html - this thread contains the issue I am facing.

I am using the following commands

ivprobit gs age foreign group tfp (xliq=l.xlq_mean) , vce(cluster id)

margins, dydx(_all) post

Could someone provide me insight into as to why the marginal effects are similar to the coefficients of IVprobit. I am using Stata 15.
