Power to avoid spurious estimation of small temporal variance in divergences when divergence times are random. The power of models (A–D) M m s B a y e s , (E–H) M U s h a p e d , (I–L) M U n i f o r m , and (M–P) M D P P to detect random variation in divergence times as simulated under the msBayes series of models. The plots illustrate the estimated dispersion index of divergence times (| τ ̂ |) from analyses of 1000 datasets simulated under each of the msBayes models, with the the estimated probability of the model inferring one divergence event, p(| τ ̂ |<0.01), given for each combination. The 22 divergence times were randomly drawn as indicated above each column of plots, where time is respresented as millions of generations ago (MGA) according to a per-site rate of 1 × 10−8 mutations per generation. Four of the six data-generating models of the msBayes series are shown; please see Additional file 1: Figure S20 for all results.
