Performance of methods in the two-population “variable tree” scenario.

For an even sampling strategy (50 individuals per subpopulation) and moderate mean migration rate ( f‾ =2.0 ) we assessed the methods’ performance across 100 replicates by recording the “true” (i.e. simulated) ratio of the migration rates f1,2/f2,1, the point estimate (posterior mean) and the 95% credible interval. a proportion of replicates for which the truth fell within the 95% credible interval. b correlation between the truth and the point estimate. c root mean square error of the point estimate.
