Dear Listers,
There is indeed a problem with margeff: average partial effects are wrong after oprobit and ologit.
After returning from holiday, I tried to find the bug, and I hope I have managed to fix it.
However, as a side effect, standard errors became too large.
Users who are interested in estimating only the partial effects and are not interested
in standard errors might download a new version of margeff as follows:
net from "http://web.uni-corvinus.hu/bartus/stata"
net install margeff, replace
I will keep working on the problem of incorrect standard errors. When ready,
an announcement will be made.
