1. Speciation rates (λ) and temporal position of rate shifts (s) are inferred under the variable rate pure-birth model, averaged over 100 phylogenies for each simulation. The marginal rates are estimated as the mean of their posterior distributions, positions of rate shifts are estimated as the modal values of their posterior distributions. Relative errors are given in parenthesis if higher than 0.05.
