Note.—The uncorrelated relaxed clock model with an UCLD yields the highest log marginal likelihood estimate (ln MLE) among the clock models being compared. In order of decreasing model fit to the data, the UCLD is followed by the exponential epoch model (TDRexp), the RLC model, the uniform epoch model (TDRuni), and the strict clock model.
