Modifications to Spatial Scan Statistics for Estimated Probabilities at Fine-Resolution in Highly Skewed Spatial Distributions
Content Type: Abstract
Estimation of representative spatial probabilities and expected counts from baseline data can cause problems in applying spatial scan statistics when observed events are sparse in a large percentage of the spatial zones (e.g.,… read more… period, some of the sparse-data zones have no counts at all. If ignored, the zero-count spatial zones will result in … number of zero count zones is a significant fraction of all the zones. One alternative method for estimating … period, some of the sparse-data zones have no counts at all. If ignored, the zero-count spatial zones will result in … -
Evaluation of Spatial Estimation Methods for Cluster Detection
Content Type: Abstract
CDC’s BioSense system provides near-real time situational awareness for public health monitoring through analysis of electronic health data. Determination of anomalous spatial and temporal disease clusters is a crucial part of… read more… data, we then applied our program to determine 1-day (i.e., spatial) clusters significant at a p-value threshold …
