Good day Stata-listers,
I want to estimate the parameters of a tobit model but with a
specificity: the two-limit tobit model where observations on  Y   are
censored from both left and right, but the points on which this model
is censored (let it be a1& a2) are unknown.
had  someone already worked on such model?
Thanks very mach in advance!!!
Amato Allah OUCHEN
