What I need to do is to combine a bunch of marginal effects in a non-linear way so as to construct a ratio along with it's standard error. *------------------ begin example ------------------ sysuse auto, clear generate wgt = weight/1000 generate pr = price/1000 tobit mpg wgt pr, ll(17) margins, dydx(*) predict(ystar(17,.)) post nlcom _b[wgt]/_b[pr] *------------------- end example ------------------- (For more on examples I sent to the Statalist see: http://www.maartenbuis.nl/example_faq ) Hope this helps, Maarten --------------------------------- Maarten L.
