Posterior model probabilities and assignment accuracy when varying the level of genetic differentiation F_ST and testing for two nonexplanatory factors (i.e., different from the ones we used for generating migration rates) are shown. Data were simulated with proportions of nonmigrant alleles set to m_ii = 0.70.
