GS⁺ Moran's I Correlograms

The Moran's I statistic is a measure of autocorrelation similar in interpretation to the Pearson's Product Moment correlation statistic for independent samples, in that both statistics range between -1.0 and 1.0 depending on the degree and direction of correlation. Different anisotropic directions appear on separate tabs.  Parameters for calculating these variograms are set in the Autocorrelation Window.
 

When the program is running, placing the mouse cursor over an autocorrelogram point will produce a box showing the number of pairs in that lag class interval, and clicking on the point will produce a Variance Cloud or h-Scattergram graph of all pairs in that interval.

Other measures of autocorrelation provided by GS+ include variograms, correlograms, madograms, rodograms, covariograms, drift, fractal dimension, and standardized, general relative, and pairwise relative variograms.
