Dear all statalists,
Thank you for clicking on my post.

What is the proper way to deal with zero-inflated and right-censored count data?

I have written a histogram of count data that takes integer values from 0 to 30, and found excess zero and bunching at 30.
I have used the zinb command to deal with zero inflation, but there does not seem to be a ul(30) option as implemented in cpoisson.
Please let me know how to deal with this in a practical way.

Thank you for taking the time to read my post.
