Dear Statalister,

I have a question on -dtobit- which I've seen it was already asked but 
nobody answered. I can't understand what exactly calculate -dtobit- with the

option -censor-. Is it a particular form of the -at(matname)- option where 
values are those of the uncensored sample or not? I guess it must be a 
different stuff because if I ask for marginal effects at the means of IV for

the uncesored sample I do not get the same results as with the -censor- 
option. Could anybody tell me what is the actual meaning of this option?

thanks
Renzo
