%description
Implements the tree-spatial scan statistic for detecting clusters that
combine both spatial and hierarchical structures, as proposed by Cancado
et al. (2025) <doi:10.1007/s10651-025-00670-w>. The method extends
Kulldorff (1997) <doi:10.1080/03610929708831995> circular spatial scan
statistic and the tree-based scan statistic of Kulldorff et al. (2003)
<doi:10.1111/1541-0420.00039> by searching for anomalies in both
geographic regions and branches of hierarchical trees simultaneously. The
package also provides standalone implementations of Kulldorff's circular
spatial scan statistic and the tree-based scan statistic. Statistical
significance is assessed via Monte Carlo simulation under a Poisson or
binomial model, with optional 'OpenMP' parallelization.
