Spatial Cluster Detection in Case-Control Datasets with the Autonomous Leaves Graph
Content Type: Abstract
Ordering-based approaches [1,2] and quadtrees [3] have been introduced recently to detect multiple spatial clusters in point event datasets. The Autonomous Leaves Graph (ALG) [4] is an efficient graph-based data structure to handle the communication… read more… and Flávia C. O.

Significant multiple high and low risk regions in event data maps
Content Type: Abstract
The Voronoi Based Scan (VBScan)[1] is a fast method for the detection and inference of point data set space-time disease clusters. A Voronoi diagram is built for points representing population individuals (cases and controls). The number of Voronoi… read more… of a map consisting of point event data, identifying all the multiple significant anomalies, which may be of high … Diamantina, Brazil; 2Statistics, Universidade Federal de Minas Gerais, Belo Horizonte, Brazil; 3Universidade … of a map consisting of point event data, identifying all the multiple significant anomalies, which may be of high …
