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)) /*******************************/ T On Fri, Aug 26, 2011 at 9:30 PM, Urmi Bhattacharya <[email protected]> wrote: > Dear Statalisters, > > I am using Stata, version 11.2 on Mac.
