## Why It Matters
SaTScan provides a focused, purpose-built implementation of scan statistics for analyzing spatial, temporal, and space-time phenomena. By packaging statistical methods for detecting and evaluating clusters into a dedicated software tool, it enables practitioners and researchers to apply consistent, repeatable analyses to datasets that vary over space and time. Because it is free software, users can access, inspect, modify, and redistribute the tool and its methods, which supports transparency and reproducibility in analytic workflows. The availability of a maintained, author-identified tool with an official website centralizes access to documentation and resources needed to run scan statistic analyses.
