Testing Spatial Symmetry Using Contingency Tables Based on Nearest Neighbor Relations

Table 20

The NNCTs for the one-versus-rest type of symmetry analysis for the Lansing Woods data (i.e., the species in question is taken as class 1 and the others combined is treated as class 2). B.O. stands for black oaks and W.O. for white oak.
