FAQ: Can tests for spatial autocorrelation be done in ArcGIS?

Question

Can tests for spatial autocorrelation be done in ArcGIS?

Answer

Yes, starting at ArcGIS 9.0, the Spatial Statistics Toolbox in ArcToolbox provides a number of tools to measure spatial autocorrelation, analyze spatial patterns (clustering or dispersion) and assess feature spatial distributions. Some of these tools are Spatial Autocorrelation (Global Moran's I), High/Low Clustering (Getis-Ord General G), Cluster and Outlier Analysis (Anselin Local Moran's I), Hot Spot Analysis (Getis-Ord Gi*), and Directional Distribution (Standard Deviational Ellipse).

Tools to measure spatial autocorrelation are not available in the Spatial Analyst extension for raster datasets.
