Linear-shaped scan statistic extends the traditional scan statistic approach proposed in Kulldorff (1999) to identify specifically linear-shaped spatial anomalous windows along linear paths. A linear path refers to a path represented by a line with a single-dimensional spatial attribute marking an observation point. Linear paths can be categorized into two types that are (1) single paths where each path is single and does not intersect with other ones and (2) linear intersecting pathswhere multiple paths can intersect with each other. A linear anomalous window then consists of observation points spread along linear paths in a window which are unusual given the behavioral attributes with respect to the rest of the data. This entry outlines the discovery of linear-shaped spatial anomalous window through scan statistic. An overview is presented to provide insights into the state-of-the-art linear-shaped scan statistic...
