Likelihood scores, harmonic means and Bayes factors approximated under Tracer for each partitioning strategy of the MrBayes 3.1.2 analyses for the combined dataset.

<p>The Bayes factors are given for each possible comparison of strategies in the four last columns of the table. The analysis with the partitioning strategy ‘BySix’ is the best analysis for the combined dataset, and is chosen for the dating analyses as a tree prior.
