> Assuming you have Stata 11, why don't you use the new margins command and see what it gives you? Older commands tend to give wrong answers because they don't know when variables are interdependent, e.g. they will plug in a 1 for one of the dummies and mean values for the others, when the others should be set to zero. This handout discusses the problems with older commands like mfx and adjust when you have multiple dummies, interaction terms and squared terms. Older commands also don't let you use the new -asobserved- option which many feel is superior to plugging in means in your calculations.
