Note. Moran’s I statistic of autocorrelation ranges from −1.0 (perfect negative autocorrelation) through 0 (no autocorrelation) to +1.0 (perfect positive autocorrelation). Geary’s C statistic of autocorrelation ranges from 0.0 (perfect positive autocorrelation) through +1.0 (no autocorrelation) to +2.0 (perfect negative autocorrelation). According to Hanneman and Riddle [42], Geary’s C statistic is more sensitive to “local” differences, while Moran’s I statistic is more sensitive to how similar or dissimilar is each pair to the overall average (i.e. “global” difference).
