Models for Zero|Inflated and Overdispersed Correlated Count Data
Models for Zero-Inflated and Overdispersed Correlated Count Data
In tobacco research, count outcomes are often measured repeatedly on the same subject and thus correlated. Such outcomes often have many ...
Models for Zero-Inflated and Overdispersed Correlated Count Data
The models presented are specifically suited for analyzing correlated count outcomes and account for zero inflation and overdispersion.
Models for Analyzing Zero-Inflated and Overdispersed Count Data
The different approaches are evaluated in terms of the ability to take into account zero-inflation (extra zeroes) and overdispersion (variance larger than ...
Models for Zero-Inflated and Overdispersed Correlated Count Data
Failure to account for overdispersion, zero-inflation, and correlation can yield incorrect statistical inferences. Thus, it is important to familiarize ...
