Jess, Yes, certainly you can do this in Stata. Have a look at: Karaca-Mandic, P., Norton, E.C., & Dowd, B. (2012). Interaction Terms in Nonlinear Models. Health Services Research, 47(1, Pt. 1), 255–274. Greene, W. (2010). Testing hypotheses about interaction terms in nonlinear models. Economics Letters, 107(2), 291-296. Flom, P.L., & Strauss, S.M.
