Well I just would like to learn which commands I can use in Stata 10 not what Tobit is about. If it is possible can you give me an example for any interpretation of Tobit which commands I should use in Stata 10?
 
I would like to say it again my question is about commands in Stata 10 not which interpretation I will do for Tobit.
