Space-Time Scan Statistics
Tests for space-time interaction or space-time clustering, described in Chapter 7, are designed for evaluating whether cases tend to come in groups or are located close to each other no matter when and where they occur. Space-time scan statistics, on the other hand, are designed for both detecting localized clusters in three dimensional space and evaluating their significance, which are extensions of purely spatial scan statistics. Recently, Kulldorff’s (2001) cylindrical space-time scan statistic has been implemented in many syndromic surveillance systems as a major analytical tool for outbreak detection.
