I am using ArcGIS 10.3 with the tool Average Nearest Neighbor from the Spatial Statistics toolbox to describe the data. I want to avoid mistakes caused by Edge Effect.

In the Ripleys K Function tool there is an option to control that (there are a few options of what to do with Edge Effect correction) but not in Average Nearest Neighbor.

How can I avoid Edge Effect mistakes while using Average Nearest Neighbor tool?

    Sorry, you would have to modify the underlying Python code to include an edge correction for NNI. – Jeffrey Evans Apr 14 '16 at 21:05
  • but the calculation seems to be from an arcgis DLL (gapy package) – Rudolf O Apr 14 '16 at 21:19
  • In my version of Desktop ArcGIS 10.2 the tool is pointing to: "C:\program files (x86)\arcgis\desktop10.2\ArcToolbox\Scripts\NearestNeighbor.py". – Jeffrey Evans Apr 14 '16 at 21:21
  • the tool is, but this is merely a wrapper. It's a phoney open source like many ESRI tools – Rudolf O Apr 14 '16 at 21:22

    Create input larger than you need and then crop your output? – jbchurchill Apr 14 '16 at 23:14
