Overdispersion is an important concept in the analysis of discrete data. Many times data admit more variability than expected under the assumed distribution. The extra variability not predicted by the generalized linear model random component reflects overdispersion. Overdispersion occurs because the mean and variance ...

WebGEEs belong to a class of regression techniques that are referred to as semiparametric because they rely on specification of only the first two moments. They are a popular alternative to the likelihood –based generalized linear mixed model which is more at risk for consistency loss at variance structure specification.
