aMaximum posterior probability estimate.b90% highest probability marginal-density.cTo determine whether the full model was significantly better than the equal migration model, the likelihood ratio (?2LLR) statistic was tested using a ��2 distribution with 1 d.f.dTo determine whether the equal migration model was better than the no migration model the ?2LLR statistic was tested using a mixed distribution of ?��21+? ��20.
