A Voronoi based scan for space-time cluster detection in point event data
Content Type: Abstract
Scan statistics are highly successful for the evaluation of space-time clusters. Recently, concepts from the graph theory were applied to evaluate the set of potential clusters. Wieland et al. introduced a graph theoretical… read more… Duczmal et al.; licensee Emerging Health Threats Journal. www.eht-journal.org 1818 at risk of 1000 individuals, 100 … Health Threats Journal LH Duczmal et al. 2011, 4:s20 www.eht-journal.org page 2/2 1919 … -
Delineating Spatial Clusters with Artificial Neural Networks
Content Type: Abstract
Multiple or irregularly shaped spatial clusters are often found in disease or syndromic surveillance maps. We develop a novel method to delineate the contours of spatial clusters, especially when there is not a clearly dominating primary cluster,… read more… [1] Kulldorff M, 1997.

Dual Graph Spatial Cluster Detection for Syndromic Surveillance in Networks
Content Type: Abstract
Early warning systems must not always rely on geographical proximity for modeling the spread of contagious diseases. Instead, graph structures such as airways or social networks are more adequate in those situations. Nodes,… read more… [1] Kulldorff M, 1997. A Spatial Scan Statistic, Comm. Statist.
