I'm using the SPP procedure to test for Complete Spatial Randomness.  The procedure appears to require a rectangular area for analysis but I would prefer to test for CSR over a circular region.  Is this possible and, if so, how?

 

Thanks,

For mapped point patterns, PROC SPP does not support circles or other arbitrarily shaped regions. However, if you had a spatial point pattern and you did not give any boundary specification, PROC SPP 'estimates' a boundary using the Ripley-Rasson estimator. However, the starting point for the Ripley-Rasson estimator is also a rectangle.
