  • Means and 95% equal-tailed credible intervals of the marginal posterior distributions of μ, r, tg, and NA estimated from the 445 Y chromosomes described in Pritchard et al. (1999). The prior values have been recomputed by us and differ slightly from the authors’ original values. CI, credible interval.
