Abstract:
|
The detection of spatial clustering and clusters for disease incidence and mortality is an essential problem in spatial epidemiology and statistical approaches have been of great interest over the past 20 years. However in the literature, most research articles focuses on the problems of the detection of hot spot clusters and ignore the problems of the detection of cool spot clusters. In this paper, we propose a method of the detection of cool spot clusters. In our case study of the Indiana colorectal cancer study, we successfully detected a cool spot around the Indianapolis area and the statistical analysis showed that this cluster was the only local cluster in the dataset.
