Quantifying spatial association between points and classes of GIS layers

ArcGIS Pro still does not have any tool to calculate spatial association of points and classes of ordinal or categorical rasters. Such statistics existed at least since 3 decades ago.

An example is application of Weights of Evidence and Contrast introduced by Fritz Agterberg and Graeme Bonham-Carter.

An overview of the Spatial Statistics toolbox—ArcGIS Pro | Documentation

would be a good extension to examine, otherwise the tools exist to put together many spatial statistical analyses. They may not be in a "one button press here" but the Analysis toolset as well as the Spatial Analyst extension have been used for years for many of these workflows.

Thanks Dan. I have been using Spatial Statistics tools.

Currently there is no tool to calculate any statistics for spatial association of points and classes of interval or categorical rasters in Spatial Statistics toolbox.

Directly no, as I indicated, but from the papers you read what processes were they using there?

mathematical equations can be readily implemented if the data are in raster format.

Perhaps citing some specific examples, rather than referring to papers, for us to look up would help.

Also, points and rasters.... sometimes getting a common data format will open up possibilities or simplify processes, for example

Zonal Statistics (Spatial Analyst)—ArcGIS Pro | Documentation

may be a preliminary step

Or maybe the points could be converted to clusters/zone.

And producing unique map combinations of areas in rasters is just a "Combine" in the Spatial Analyst extension, and condition checking is via "Con" plus other options.

Then of course, there is always coding
