I wanted to obtain marginal effects of interaction terms in Tobit regression. Altough there are some examples given by Stata FAQ page http://www.stata.com/support/faqs/statistics/marginal-effects-after-interactions/ there is no example for Tobit estimation. I am particularly interested in marginal effects of quadratic term in Tobit? Can you explain how to do it for Tobit?
