Manuel, us your margeff updated? You write..."His suggestion is to use the following command: > Margeff, dummies (B *) > where D are all dummies for which you want to calculate the marginal > effects." are dummies B or D? I'm using margeff after ologit and it works fine. Try to write the name of your dummies. ologit vardep vars margeff, at (mean) dummies(name_dummy1) Best Joao Lima 2008/4/22, [email protected] <[email protected]>: > Dear users, > > My question is following one: I do not know how to calculate average > marginal effects (AME) for categorical variables with more than two > categories? > In my ordered logit model, I have a dependent variable with 4 categories and > 5 categorical explanatory variables, 3 of them with more than two > categories.
