Andresen)Implements the area-based nonparametric spatial point pattern test of Andresen (2009) <doi:10.1016/j.apgeog.2008.12.004> for comparing two spatial distributions of events aggregated to areal units, with the applications and extensions reviewed in Andresen (2016) <doi:10.1177/2059799116630659>. Unit-level inference uses bounded Monte Carlo bootstrap p-values, with marginal confidence interval overlap retained as an option. Global similarity is summarised by the robust S index, accompanied by a test of whether two patterns are more different than two realisations of a single process, and a test of the spatial arrangement of the differences. A longitudinal extension compares each period of a time series against a base period and classifies unit-level trajectories. Publication-ready maps can be redrawn with user-chosen layouts.https://github.com/r-universe/martinandresen/actions/runs/40680091600Tue, 27 Oct 2026 15:00:11 GMTsppt1.0.0successhttps://martinandresen.r-universe.devhttps://github.com/cran/spptsppt.Rmdsppt.htmlComparing two spatial patterns with sppt()2026-10-27 15:00:112026-10-27 15:00:11sppt_longitudinal.Rmdsppt_longitudinal.htmlLongitudinal change with sppt_longitudinal()2026-10-27 15:00:112026-10-27 15:00:11
