Abstract : Standard methods for the analysis of cluster-correlated count data fail to yield valid inferences when the study is finely stratified and the interest is in assessing the intracluster correlation structure. We present an approach, based upon exactly adjusting an estimating function for the bias induced by the fitting of stratum-specific effects, that requires modeling only the first two joint moments of the observations and that yields consistent and asymptotically normal estimators of the correlation parameters.

Keywords : Profile estimating function Plug-in bias Poisson overdispersion Generalized estimating equation Household aggregation Intracluster correlation Nuisance parameters Small geographic area
