Hello,
I am trying to obtain marginal effects on ivprobit.
As I understand it, I need to use the post-estimation command mfx, predict(p). "mfx" alone will not work (it does not give the marginal effects, I believe). When I use the predict(p) command, however, Stata reports that the expression is unsuitable for calculating standard errors. I know I can force it, but Stata says this may not be recommended. Is it okay to use force if the relative difference is very small?
Any recommendations on how I can obtain the marginal effects of an ivprobit and good standard errors?
Much appreciated,
Matt
