Assessing the effect of model specification and prior sensitivity on Bayesian tests of temporal signal
Fig 5
Marginal prior distributions and pairs plots.
The grey histograms correspond to the parameter labelled at the bottom of each column; effective population size (pop. size, θ), tree length, root height, and the evolutionary rate (evol. rate). The prior for θ here is a Uniform distribution between 0 and 103, while that for the evolutionary rate is a CTMC-rate reference prior. Note that the tree length and root height have units of time, the evolutionary rate is in subs/site/time, and θ is proportional to units of time.
