Interactive Detection of Spatial Clusters
Content Type: Abstract
Geographic visualization methods allow analysts to visually discover clusters in multivariate, spatially-referenced data. Computational and statistical cluster detection techniques can automatically detect spatial clusters of high values of a… read more… The authors propose that the two approaches can be com- plementary; and present an integration of the GeoViz … Fur- ther research is needed to uncover the optimal con- nections between geographic visualization and clus- … Information: Frank Hardisty, hardisty@psu.edu http://www.geovista.psu.edu/grants/cdcesda/software/ [1] A.

Automated Generation of Hypothesis of Processes Causing Clusters
Content Type: Abstract
Computational and statistical methods for detecting disease clusters, such as the spatial scan statistic, have become frequently used tools in epidemiology. However, they simply tell the user where a cluster is, and leave the… read more… dispersion within a river. The pattern matching module com- pares the shape of the detected cluster with the shapes … Source code available at http://code.google.com/p/clusterer/ Cluster Detection Pattern/Process Database …
