Spatial Cluster Estimation and Visualization Using Item Response Theory
摘要
In recent years Kulldorff’s circular scan statistic has become the most popular tool for detecting spatial clusters. However, window-imposed limitation may not be appropriate to detect the true cluster. To work around this problem we usually use complex tools that allow the detection of clusters with arbitrary format, but at the expense of an increase in computational effort. In this chapter we describe a methodology that assists the detection of unconnected and arbitrarily shaped clusters and that provides a measure of uncertainty in the design of such clusters.
