EV.Nii: Expected Values of the Self Entries in a Species...

In nnspat: Nearest Neighbor Methods for Spatial Patterns

Expected Values of the Self Entries in a Species Correspondence Contingency Table (SCCT)

Description

Returns a vector of length k of expected values of the self entries (i.e., first column) in a species correspondence contingency table (SCCT) or the expected values of the diagonal entries N_{ii} in an NNCT. These expected values are valid under RL or CSR.

The argument ct can be either the NNCT or SCCT.

Usage

EV.Nii(ct)

Arguments

ct	The NNCT or SCCT

Value

A vector of length k whose entries are the expected values of the self entries (i.e., first column) in a species correspondence contingency table (SCCT) or of the diagonal entries in an NNCT.
