I wanted to obtain marginal effects of interaction terms in Tobit regression. Altough there are some examples given by Stata FAQ page 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? 

sysuse auto,clear
generate wgt=weight/1000
tobit mpg c.wgt##c.wgt, ll(17)
margins, dydx(wgt)
margins, dydx(wgt) at(wgt=(1.75(0.5)4.75)) vsquish
