Hi Marteen,
thanks for your response. It seems I need to use pu0 to resolve the mystery however now having the same problem with normal tobit. I would like to get the marginal effects after tobit but pu0 option does not work. When I use "estpost margins, dydx(*) atmeans", it gives again the same coefficients with the tobit model. please can you advice?
kind regards
Ozgur
