I have a point data set representing 'Plants' across a vast range. The point data set does not contain a boundary... its just a collection of points. I would like to perform a Multi-distance Spatial Cluster Analysis (Ripleys K Function) on my data set. I am Utilizing ArcMap10 on a Windows 7 machine. Here are the parameter inputs: featureclass_plants output table Number of distance bands: 10 Confidence Interval: 99_permuations Display results checked Weight Field: Blank Beginning Distance: 0 Distance Increment: 2 Boundary Correction Method: Ripley_edge_correction_formula Study Area Method: Minimum_enclosing_rectangle The calculation FAILS. The error that it throws is: <type 'exceptions.KeyError'>:28L The problem is with the Boundary Correction method. If I use NONE or SIMULATE OUTER BOUNDARY VALUES, the calculation works. If I use RIPLEYS EDGE or REDUCE ANALYSIS AREA the calculation fails. I am assuming it is a BUG in Arc10 because it works fine in 9.X. Any suggestions?? Thanks
