Zero-Inflated Poisson and Negative Binomial Models with GLMMadaptive

August 27, 2018 | Dimitris Rizopoulos

Clustered/Grouped Count DataOften cluster/grouped count data exhibit extra zeros and over-dispersion. To account for these features, Poisson and negative binomial mixed effects models with an extra zero-inflation part are used. These models entail a logistic regression model for the extra zeros, and a Poisson or negative binomial model ... [Read more...]
