Effect of accounting for phylogenetic uncertainty on rate estimates. Comparison of the speciation rate estimated on 10 trees randomly sampled from the posterior distribution (A), and averaged over 100 trees (B). The dashed line indicates the maximum likelihood estimate based on the consensus tree. Error bars represent the 95% highest posterior density (HPD) interval of the rate estimates. Accounting for phylogenetic uncertainty results in an average increase of the width of the 95% HPD by 30% (B).
