WebHierarchical Models. In this section, we use the mathematical theory which describes an approach that has become widely applied in the analysis of high-throughput data. The … Webmodel).Breslow(1984) discusses these types of models and suggests several different ways to model them. Hierarchical Poisson models have been found effective in capturing the overdispersion in data sets with extra Poisson variation. Hierarchical Poisson regression models are expressed as Poisson models with a log link and a normal vari-
