st: evaluating marginal effects in trivariate probit model

["Xie, Jia" <jiaxie@indiana.edu>]

Dear Sir or Madam,
   I am using trivariate probit model, the command I am using is
"mvprobit", however, there is problem for me to get the marginal
effects. Can you tell me how to evaluate marginal effects after a
trivariate probit regression? Many thanks.
   Best
   Jia
