WebWhat is a p-value? When the Input Feature Class is not projected (that is, when coordinates are given in degrees, minutes, and seconds) or when the output coordinate system is set to a Geographic Coordinate System, distances are computed using chordal measurements. WebThe Plugin implements Local Indicators of Spatial Association (LISA) statistics to perform hotspot (Getis-Ord Gi*) and clusters (Moran's I) analysis and links them to maps. Input data must be a shapefile of points or polygons with an associated projected coordinate system and (at least) one numeric attribute.
