ind.nnsym {nnspat}

Index Matrix for Computing the Covariance of Dixon's Overall NN Symmetry Test

Description

Returns the index matrix for choosing the entries in the covariance matrix for NNCT used for computing the covariance for Dixon's NN symmetry test. The matrix is k(k-1)/2 \times 2 with each row is the i,j corresponding to N_{ij} in the NNCT.

Usage

ind.nnsym(k)

Arguments

k

An integer specifying the number of classes in the data set

Value

The k(k-1)/2 \times 2 index matrix with each row is the i,j corresponding to N_{ij} in the NNCT
