Runs Getis and Ord’s G Local (Gi or Gi*) statistic on the geometry given the weights and level. Getis and Ord’s Gi and Gi* statistics are used to identify data points with locally high values (hot spots) and low values (cold spots) in a spatial dataset. The ST_WeightedDistanceBand and ST_BinaryDistanceBand functions can be used to generate the weights column.
