Abstract

Among the numerous approaches proposed for the analysis of spatial processes, the autocorrelation index (Geary, 1954) introduced by Cliff & Ord (1973) possesses remarkable properties. For any given variable (presence/absence, cover, quantitative measures of abundance) and random distribution of sampling points in space, this index tests the null hypothesis of absence of correlation for values recorded at two neighbouring points, using a non parametric model for equiprobability of N ! attributions of N numerical values at N sampling points.
