Effect of neglecting phylogenetic uncertainty on estimates of divergence times under local clock models for the marsupial data.

Results for local clock models, MSS and HOPACH, are given both for the maximum a posteriori (MAP) tree and as a posterior probability weighted average over the 95% credibility set (CS) of topologies sampled from the appropriate target distribution. The uncorrelated models from BEAST (UCLN: uncorrelated lognormal) integrate over tree topologies, branch lengths and parameters of the substitution model. Times are in million years ago. SSD are computed with respect to UCLN (baseline).

局部时钟模型（local clock models）、MSS与HOPACH的结果，既以最大后验（maximum a posteriori, MAP）树的形式给出，也通过对从恰当目标分布中采样得到的拓扑结构的95%置信集（credibility set, CS）进行后验概率加权平均的方式呈现。来自BEAST的不相关模型（UCLN：不相关对数正态（uncorrelated lognormal））会对树拓扑结构、分支长度以及替换模型的参数进行积分。时间单位为百万年前，平方偏差和（SSD）以UCLN作为基准进行计算。
