Thanks to Kit Baum, an update to -margeff- program has been added to SSC.
-margeff- estimates fasly both average marginal effects and marginal effects at the
mean after several categorical dependent variable models.
The new version (5 may 2005) features some new options, and the syntax became
more similar to that of -mfx-.
Besides, the new version corrects the following problems of the previous distributions:
1. marginal effects after -biprobit- were wrong for some outcomes,
due to a sign error in the program.
2. marginal effects after -oprobit- and -ologit- were wrong for the intermediate
outcomes, due to a small error in the program.
3. The 22 april 2005 version produces wrong results if the user specified the
dummies() option.
I apologize for any mistakes that might have occured in published work.
