From: A comparison of methods for estimating substitution rates from ancient DNA sequence data
a Uncertainty in Bayesian estimates of substitution rates across 12 simulation conditions, as measured by the width of the 95% credibility interval of the estimate divided by the rate used for simulation. One hundred data sets were produced by simulation under distinct evolutionary conditions and analysed using BEAST. b Relationship between phylogenetic stemminess (proportion of overall tree length represented by internal branches) and the error in the Bayesian median rate estimates
