I have conducted an Ordinary Least Squares (OLS) and Geographically Weighted Regression (GWR) analysis in ArcGIS where I have tried to predict biodiversity patterns in an area. When I examine the results with Spatial Autocorrelation the residuals tends to be clustered with a fairly high Z-value.
The result from the GWR, however, tends to be the expected when I visualize it. How do I handle the clustering? What problems does it creates, IS there any problems?
