題:Spatial disease mapping models associated with cluster detection by heterogeneity measure

Abstract

   The mapping of disease incidence has long been a part of public health and epidemiology.In this paper, we develop a disease mapping method to cover two main aims: (1) to build an estimation procedure on an integrated model so that we can estimate relative risk in each region and estimate association between relative risk and potential risk factors, and (2) to develop a cluster detection method that can be used to find local features of elevated risks. We propose a new approach to identify clusters that have abrupt changes in arbitrary shapes while accounting for covariates and spatial information in a multi-dimensional space. A set of complementary models is built to compare heterogeneity of the slopes between a candidate cluster and its complement with covariates and spatial correlation being integrated into the models. We use a simulation study and an enterovirus data example to illustrate the proposed method.
