Hello everyone,
I run a logit model with an interaction between two dummy variables. I use the user-written command -inteff- to estimate marginal effects based on Norton et al.'s (2004) paper published in The Stata Journal. The results that I obtain are similar by applying margins command:
where a and b are the two dummy variables. I also want to interpret the results in terms of odds-ratio. I have read the paper of Buis (2010) from The Stata Journal which suggests the following:
where the last line gives the marginal effect in terms of odds-ratio (I want to see the marginal effect of my interest variable, a, in the presence of b vs. the absence of b). However, I'm not sure whether my approaches are correct. Any suggestion will be highly appreciated.

Code:
logit y x i.a##i.b, vce(robust) margins r.a#r.b
Code:
logit y x i.a##i.b, vce(robust) or margins, over(a b) expression(exp(xb())) post lincom 1.a#1.b - 1.a#0.b
