I have a few thoughts:

-Steve

I am using zinb to estimate level of psychological distress (scoresrange from 0-24) using various demographic variables and measuresof use of the Internet. I've used -countfit- to compare variouscount models and the results support zinb as the best fitting model.I am uncertain, however, about how to justify the variables that Iinclude in the zero-inflated part of the model. I've read journalarticles that have used zinb, read the book by Freese and Long, andsearched the Internet and Statalist but I have not been able tofind any detailed recommendations or procedures. Can anyone suggestany other sources (books or journals) that provide an explanationor a good example of this process?Ideally I would like to find a good source that I can cite in thepaper -- but I appreciate any suggestions about this you might have.Thanks for you help, Tim ----------------------------------------------------- Timothy M.
