Running Two Limit Tobit model

[Straso Jovanovski]

Hello,
I have been attempting to run a Two Limit Tobit model on my data. I have a relatively large dataset (over 380,000 observations) nested within 310 regions. The dependent variable I use in this instance is a count variable having excess dispersion at the margins (it takes on the values 0 through 30, days of the month; number of days a respondent reports their well-being taking on a given state). Over 60% of responses take on the value of 0. Then there is a more modest spike occurring at 30. I am setting my lower limit to be 0 and upper limit at 30.
Below is what I get:

. estimates clear

r(3900);

end of do-file

r(3900);

Thank you for any help.
