exclusionPower {relSim}

Calculate the exclusion power of a multiplex by locus

Description

Calculates the exclusion power

1-2\left(\sum_{i=1}^{n_l}p_i^2\right)^2-4\sum_{i=1}^{n_l}p_i^4

at each locus for a set of allele frequencies.

Usage

exclusionPower(Freqs)

Arguments

Freqs

A list containing two vectors and a list, called loci, counts, and freqs. The elements of loci are the loci present in the multiplex. The elements are freqs a vectors of allele frequencies for the locus. The elements of counts are irrelevant here.

Value

The exclusion power for each locus.
