Estimates of demographic parameters from IMa analysis with results of model comparisons.

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 χ2 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 ½χ21+½ χ20.
