Dear list, I would like to fit a negative binomial regression model as described in "Byers AL, Allore H, Gill TM, Peduzzi PN., Application of negative binomial modeling for discrete outcomes: a case study in aging research. J Clin Epidemiol. 2003 Jun;56(6):559-64" to my data in which the response is count data. There are also 10 predictors that are count data, and I have also 3 categorical and 2 continious predictors. There is overdispersion in the distribution of the response variable (mean=2.8, variance=28) as well as in predi...

The article that is most clear ### on how this can be done to estimate a proportional odds logistic ### model is ### Stephen R. Cole, Paul D. Allison, and Cande V. Ananth, ### Estimation of Cumulative Odds Ratios ### Ann Epidemiol 2004;14:172?178. ### They claim that one can recode an n-chotomy into n-1 dichotomous ### indicators. Each observation in the original dataset begets n-1 ### lines in the augmented version. After creating the dichotomous ### indicator, one uses an ordinary dichotomous logit model to ### estimate...
