| Title | Accessing the marginal effects vector after dprobit | |
| Author | William Sribney, StataCorp | |
| Date | April 1997 |
. dprobit y x1 x2 ...
. matrix b = get(_b)
. scalar fz = (1/sqrt(2*_pi))*exp(-(S_E_xbar^2)/2)
. matrix df = fz*b
. matrix list df
This should give the correct results for continuous variables if you used the option at(xbar) (the default). If you used at(some number), replace it with invnorm(some number).
See Stata 6.0 Reference Manual, Volume 3, pages 78–79 for the formulas and for details (and how to do the computation for dummy variables).
