EV.Nii: 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

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.

Arguments
