st: xttobit with multiple upper limits

[Andrea Kutinova <andrea.kutinova@canterbury.ac.nz>]

Dear Stata users,

I'm estimating an xttobit model with multiple treatment groups and the
dependent variable has a different upper bound for each treatment group.
Is there a way to allow for different ul() by treatment group
membership?

I'd appreciate your suggestions very much!
Andrea
