A Bayesian scan statistic for spatial cluster detection
Document Type: Paper
Tags: Biosurveillance, Spatial Scan, Spatial Statistics
This paper develops a new Bayesian method for cluster detection, the ?Bayesian spatial scan statistic,? and compares this method to the standard (frequentist) scan statistic approach on the task of prospective disease surveillance.
A Bayesian spatial scan statistic
Document Type: Paper
Tags: Biosurveillance, Spatial Scan, Spatial Statistics
We propose a new Bayesian method for spatial cluster detection, the ?Bayesian spatial scan statistic,? and compare this method to the standard (frequentist) scan statistic approach. We demonstrate that the Bayesian statistic has several advantages over the frequentist approach, including increa...
A Fast Multi-Resolution Method for Detection of Significant Spatial Disease Clusters
Document Type: Paper
Tags: Biosurveillance, Clustering, Kd-trees and Ball-trees, Efficient Statistical Algorithms, Applications
Given an N x N grid of squares, where each square has a count and an underlying population, our goal is to find the square region with the highest density, and to calculate its significance by randomization. Any density measure D, dependent on the total count and total population of a region, ca...
A Fast Multi-Resolution Method for Detection of Significant Spatial Overdensities
Document Type: Paper
Tags: Biosurveillance, Statistical Data Mining for Astrophysics, Clustering, Efficient Statistical Algorithms, Kd-trees and Ball-trees, Applications, Spatial Statistics
Given an NxN grid of squares, where each square s_ij has count c_ij and an underlying population p_ij, our goal is to find the square region S with the highest density, and to calculate the significance of this region by Monte Carlo testing. Any density measure D, which depends on the total coun...

Artur Dubrawski considers himself a scientist and a practitioner. He has been tainted with real world entrepreneurial experiences. He had started up a successful company specializing in integration and deployment of advanced control systems and technological devices. He had also been affiliated ...
A Study into Detection of Bio-Events in Multiple Streams of Surveillance Data
Document Type: Paper
Tags: Biosurveillance, Multiple Streams
This paper reviews the results of a study into combining evidence from multiple streams of surveillance data in order to improve timeliness and speci?city of detection of bio-events. In the experiments we used three streams of real food- and agriculture-safety related data that is being routinel...
Bayesian Network Anomaly Pattern Detection for Disease Outbreaks
Document Type: Paper
Tags: Biosurveillance, Bayesian Networks, WSARE
Early disease outbreak detection systems typically monitor health care data for irregularities by comparing the distribution of recent data against a baseline distribution. Determining the baseline is difficult due to the presence of different trends in health care data, such as trends caused by...
