Hi, When Stata calculates AMEs for logit models with dummy
variables, does it "know" that the dummy variable is discrete, and
calculate its marginal effect accordingly?
Bob Reed
If you use factor variable notation it does, e.g. if you do
logit y i.x1 x2 x3
margins, dydx(*)
x1 will be treated as discrete/categorical while x2 and x3 will be
treated as continuous (even if they happen to be coded as 0/1 dichotomies).
