Geovisual analytics to enhance spatial scan statistic interpretation: an analysis of U.S. cervical cancer mortality
BACKGROUND Kulldorff's spatial scan statistic and its software implementation - SaTScan - are widely used for detecting and evaluating geographic clusters. However, two issues make using the method and interpreting its results non-trivial: (1) the method lacks cartographic support for understanding the clusters in geographic context and (2) results from the method are sensitive to parameter cho...
متن کاملVisual Analytics of Spatial Scan Statistic Results
Kulldorff’s scan statistic[1] is a spatial scan statistics method for detecting and evaluating statistically-significant, spatial clusters (e.g. disease, crime, etc). The method and its software implementation – SaTScan – is used widely in an increasing number of applications including epidemiology and other research fields. Here, we abbreviate the method as SaTScan method. Many researchers hav...
متن کاملA Geovisual Analytics Approach to Spatial Multiple Objective Optimization
Multiple objective genetic algorithms (MOGA) are heuristics that have seen relatively little use in geographic information science and spatial decision support in comparison to other geocomputational methods, despite their potential to generate robust alternative options for decision making. MOGA based decision analysis relieves the burden of a priori preference specification by an analyst, but...
متن کاملA Bayesian Spatial Scan Statistic
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 increased power to detect clusters and (since randomization testing is unnecessary) much faster runtime. We ...
متن کاملAnalysis of Mapping Techniques on a Spatial Scan Statistic
The discovery of anomalous regions within spatially oriented data can provide valuable insights to the study of disease prevention, crime, and socioeconomic inequality. Spatial scan statistic methods are a common tool used within these fields to discover areas of a data set that have significant variation when compared to the background distribution. However, the effects of data representation ...
