New approaches to studying problem behaviors: A comparison of methods for modeling longitudinal, categorical adolescent drinking data.
Developmental Psychology. Vol 45(3), May 2009, 652-676.

In this article, the authors present several currently available modeling options, all of which make appropriate distributional assumptions for the observed categorical data. .
