funs.pijPij | R Documentation |
The ancillary probability functions used in computation of the variance-covariance matrices
of various NN spatial tests such as NNCT tests and tests based on other contingency tables.
These functions can be classified as pij
and Pij
type functions. The pij
functions are for individual
probabilities and the corresponding Pij
functions are the summed pij
values. For example p_{iijk}
is the probability of any 4 points with 2 from class i, and others are from classes j and k.
These probabilities are for data from RL or CSR.
