Strict and relaxed clock models are used in Bayesian estimation of divergence times. We examined whether: i) strict clock models are generally more appropriate in shallow phylogenies where rate variation is expected to be low, ii) the …
WebThis means that after adding data, our belief in a strict clock increased from 50% to about 70%, a very modest change. The data in this tutorial suggests that a strict clock applies to pocket gophers, but falls far short of any standard of proof. Obtaining an estimate of the phylogenetic tree.

WebMay 16, 2007 · priors under the relaxed lognormal model? Following the manual, ucld.mean has the same units as clock.rate under a strict clock model, while meanRate estimates (according to the Beauti interface) the "mean rate of evolution across the whole tree." There is no further annonation for the latter in the manual. Basically, it seems that if
