fuzzy c-means cluster analysis

Question

Hello,

Does ArcGIS Desktop 10 with Geostatistical Analyst perform fuzzy c-means cluster analysis?  I am currently working with a procedure that requires I export tables to the R environment to do this. Would be nice if I can stay inside ArcGIS.

Thank you,
Clint

In ArcGIS Pro we do not have a tool for fuzzy c-means clustering method. Spatially Constrained Multivariate Clustering can return frequency based probabilities of cluster membership if you use the Permutations to Calculate Membership Probabilities setting. Density Based Clustering (http://pro.arcgis.com/en/pro-app/tool-reference/spatial-statistics/densitybasedclustering.htm) using the HDBScan Clustering Method will also return frequency based Membership Probabilities.

Thanks a lot, Ryan.

I would like to ask one more question, is there any tool in ArcGIS Pro that can process fuzzy c-means clustering or other kinds of clustering?

Hello Huanglei Pan,

In ArcMap 10.6 the tool is called Grouping Analysis (Grouping Analysis—Help | ArcGIS Desktop)

In ArcGIS Pro we have split Grouping Analysis into non spatial (Multivariate Clustering—ArcGIS Pro | ArcGIS Desktop )  and spatial (Spatially Constrained Multivariate Clustering—ArcGIS Pro | ArcGIS Desktop) versions.

I hope this helps,

Ryan
