Hello,
I think you can simply run
tobit y x, ll
Stata then takes as censoring value the minimum observed in the data
(in your case, 0).
Hope this helps,
Fabrizio
Hi,
I have a dependent variable that is left-censored in the following
sense. Any values equal to 1 or above are recorded with their actual
value. Any values less than 1 are coded as zero. I thought I had to
run the estimation as
tobit y x, ll(1)
However, if I do this, then Stata also counts all observations with
value of 1 as censored. Should I therefore run
tobit y x, ll(0) or something like tobit y x, ll(0.99)?
Any help greatly appreciated. Best, Eric Neumayer
