Betreff: st:marginal effects after ssm command

Hi statalist, 


We are using ssm command to estimate an ordered model with sample selection.
We want to estimate the marginal effects of our explanatory variables. We
use mfx command after the ssm command but this gives us the same values as
the estimated coefficients.  It seems that mfx is not given us the marginal
effect. Does anybody know which is the appropriate command to get the
marginal effects when using ssm?

Thank you very much,
