st: standard error calculation of marginal effects from ivprobit

[Alejandro Delafuente <alejandro.delafuente@st-antonys.oxford.ac.uk>]

Hi everyone, can someone tell me how to get the standard errors for the 
marginal effects obtained after an ivprobit estimation. Am using the following 
command: mfx compute, predict(p)
but Stata tells me that predict() expression p is unsuitable for standard-error 
calculation; it imposes nose option.

Many thanks,
Alejandro
