Extended Data Table 2 Model selection for BEAST analyses

  1. a, Marginal likelihoods calculated with path-sampling (PS) and stepping-stone sampling (SS) for combinations of three coalescent tree priors (constant size population, exponential growth population, and Skyline) and two clock models (strict clock and uncorrelated relaxed clock with log-normal distribution). The Bayes factor is calculated against the baseline model, a constant size tree prior and strict clock. b, Mean estimates and 95% credible intervals across evaluated models for the clock rate, date of tree root, and tMRCAs of the four regions shown in Fig. 2c. Under a Skyline tree prior, the use of strict and relaxed clock models yields similar estimates.
