Abstract—We analyze the existence of some regularities in the spatial distribution of labelled individuals. Several indexes for measuring the relationship between the non-ordered categorical variable and the geolocation variables are evaluated together with a new proposed one. Simulations suggest that this new index is quite robust and efficient when compared with the previously known ones.

Index Terms—Geolocated date, correlation analysis, categorical variables, voronoi tessellation, entropy.
