Could someone please explain why these two versions of margfx do not work?
According to the help, they are equivalent, but I get a cryptic syntax
error after the second.

Margfx also sometimes gives the AME for a subset of the explanatory
variables without any indication of why it dropped the others. The probit
runs without dropping anything.

If someone could explain this, I would be most grateful. This is my code:

use auto, clear
gen sex=round(uniform(),1) /* I wanted to add a binary var on RHS */

/* Method 1 */
margfx for*, contin(price mpg headroom) binary(sex) model(probit)

/* Method 2 */
probit for* price mpg headroom sex
margfx, qui
