qualitySubpops {ConnMatTools}

Quality measure for subpopulation division

Description

A measure of the leakage between subpopulations for a given division of the connectivity matrix into subpopulations. This statistic is equal to 1 - mean(RLR) of the reduced connectivity matrix, where RLR=relative local retention (relativeLocalRetention), i.e., the fraction of settling individuals that originated at their site of settlement.

Usage

qualitySubpops(subpops.lst, conn.mat)

Arguments

subpops.lst

A list whose elements are vectors of indices for each subpopulation. If a vector of integers is given, then subpopsVectorToList is applied to convert it to a list of subpopulations.

conn.mat

A square connectivity matrix.

Value

The quality statistic.

A smaller value of the quality statistic indicates less leakage.
