I have two layers, which visually have spatial correlation. Does anyone know if ArcGIS has any analysis test to test if there is any significant correlation between those two layers?
Did you examine or rule out any of the tools in this link
Also, the spatial statistics toolbox may help:
An overview of the Spatial Statistics toolbox—Help | ArcGIS for Desktop
Is that available in ArcGIS Online?
I believe it's just with ArcMap and ArcGIS Pro - not ArcGIS Online! I wanted to make sure they were aware, just in case it was helpful.
