WebJan 1, 2024 · Geary’s C ranges from 0 to a positive value. The value of C is 1 in the absence of spatial autocorrelation. A low value of C(0 < C < 1) represents a positive spatial autocorrelation and approaches zero for strong autocorrelation. A high value (C > 1) represents negative spatial autocorrelation with greater values corresponding to a strong … WebGeary’s C • Value typically range between 0 and 2 • If value of any one zone are spatially unrelated to any other zone, the expected value of C will be 1 – Values less than 1 (between 1 and 2) indicate negative spatial autocorrelation • Inversely related to Moran’s I • Does not provide identical inference because it emphasizes the mary ruth andrews https://dreamsvacationtours.net
