How to graph the averge marginal effect of probit model (spline approach)

[David Lu]

Dear Statalist,

I am using -mkspline- and -probit- command to calculate the average marginal effect of probit model.

below are my command:

mkspline HAF21 0 HAF22= HAF2 

probit open  l.HAF21 l.HAF22 l.lncv222 l.lncv1 l.HERF l.cv41   l.cv61 l.cv7 i.yr indc1-indc28,vce(robust)  nocon
margins , dydx(l.HAF21 l.HAF22 l.lncv222 l.lncv1 l.HERF l.cv41   l.cv61 l.cv7) atmeans post

In order to display it by graph like this, is there any command in stata to graph the averge marginal effect of probit model (spline approach)?

Thanks in advance,
David

After margins, you can use marginsplot. If you really have difficulty, you can do a set of margins, and then copy the margins along with x variables into a new set of variables to plot.
