Estimates of the time of the most recent common ancestor (TMRCA) of <i>Rice yellow mottle virus</i> by Bayesian coalescent methods under several molecular clock and population genetic models implemented in BEAST

a95% lower, mean, and 95% upper values of the highest posterior density (HPD) interval that contains 95% of the marginal posterior distribution. bMarginal likelihoods, in loge units, were calculated via importance sampling using the harmonic mean of the sampled likelihoods (with the posterior as the importance distribution).a. 包含95%边缘后验分布的最高后验密度（Highest Posterior Density, HPD）区间的95%下限、均值与95%上限。 b. 自然对数尺度（loge单位）下的边缘似然，通过重要性抽样法计算，以采样似然值的调和均值作为估计量，且以后验分布作为重要性分布。
