Fast subset scan for multivariate spatial biosurveillance
Content Type: Abstract
The spatial scan statistic detects significant spatial clusters of disease by maximizing a likelihood ratio statistic over a large set of spatial regions. Several recent approaches have extended spatial scan to multiple data streams. Burkom… read more… scan statistic. Commun Statist: Theory and Methods 1997;26:1481–96. 2 Burkom HS.

Scalable Detection of Irregular Disease Clusters Using Soft Compactness Constraints
Content Type: Abstract
The spatial scan statistic [1] detects significant spatial clusters of disease by maximizing a likelihood ratio statistic F(S) over a large set of spatial regions, typically constrained by shape. The fast localized scan [2] enables scalable… read more… scanning (LTSS) property to efficiently search over all subsets of each location and its k - 1 nearest … to spatially compact clusters while still considering all subsets within a given neighborhood. Objective We … scanning (LTSS) property to efficiently search over all subsets of each location and its k�1 nearest neighbors. …
