Note that by default -margins- computes the average marginal effects,
and -mfx- computes marginal effect at the means of the covariates.
Here are the equivalent commands:
/*******************************/
webuse fullauto, clear
ologit rep77 foreign length mpg
mfx, predict(outcome(1))
ologit rep77 i.foreign length mpg
margins, dydx(*) atmeans predict(outcome(1))
/*******************************/
