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… University of Belo Horizonte, Minas Gerais, Brazil E-mail: duczmal@est.ufmg.br Objective We describe a method for … -
A new interpretation of the inference test for the spatial scan statistic
Content Type: Abstract
Spatial cluster analysis is considered an important technique for the elucidation of disease causes and epidemiological surveillance. Kulldorff's spatial scan statistic, defined as a likelihood ratio, is the usual measure of the strength of… read more… Int J Health Geograph. 2011;10:47. *Luiz Duczmal E-mail: duczmal@ufmg.br (page number not for citation purpose) … -
Spatial cluster detection through constrained dynamic programming
Content Type: Abstract
The spatial scan statistic [1] is the most used measure for cluster strenght. The evaluation of all possible subsets of regions in a large dataset is computationally infeasible. Many heuristics have appeared recently to compute approximate values… read more… Int J Health Geograph. 2010;9:55. *Luiz Duczmal E-mail: duczmal@ufmg.br (page number not for citation purpose) …
