Thanks David,
I am lucky enough to have STATA v8 but not panel tobit with fixed effects. In my case
there are 27 right censored observation. I was just wondering can you or other users
give me a sample command to run fixed effect and random effect model. Is it just xtreg
with fe option?

Yaseen,
I am also doing some efficiency estimation and i use tobit as a robustness
check. very few of our scores are censored (at zero or 1), so we are
using other models (ols, fixed and random effects). You might want to
make sure ols (or tobit) is correct for your data, fixed or random effects
may be better.
Along the same lines, is it possible to run fixed effects tobit model with
stata? I am using v7 and that allows a random effects tobit, but not
fixed effects (as far as i can tell).
thanks in advance.
