Spatial Scan Statistic: Selecting Clusters and Generating Elliptic Clusters |
Lasse Engbo Christiansen, Jens Strodl Andersen
|
| Abstract | The spatial scan statistic is widely used to search for clusters. This paper shows that the usually applied elimination of overlapping clusters to find secondary clusters is sensitive to smooth changes in the shape of the clusters. We present an algorithm for generation of set of confocal elliptic clusters. In addition, we propose a new way to present the information in a given set of clusters based on the significance of the clusters. |
