  1. ** Non-spatial correlation is significant at p< 0.01 (2-tailed)
  2. *spatial correlation is significant at pseudo p < 0.05 for conditional 999 permutations
  3. # Spatial correlation is most appropriate but the spatial correlation was much smaller than the non-spatial correlation and the departure from independence is consistent but weak. The assumption of spatial independence may have affected the non-spatial correlation result
