May 24, 2016 · Download r8s for free. Divergence time estimation on phylogenies. This package implements several methods to infer divergence times on a molecular phylogeny, using penalized likelihood, maximum likelihood and nonparametric rate smoothing methods.

This is a program for estimating absolute rates (“r8s”) of molecular evolution and divergence times on a phylogenetic tree. It implements several methods for estimating these parameters ranging from fairly standard maximum likelihood methods in the context of global or local molecular clocks to more experimental semiparametric and

Jan 22, 2003 · Unlike most programs for rate inference or phylogenetics, r8s permits users to convert results to absolute rates and ages by constraining one or more node times to be fixed, minimum or maximum ages (using fossil or other evidence).

Mar 25, 2021 · r8s 是美国加利福尼亚大学戴维斯分校的进化生物学家 Mike Sanderson 在2003年编写的用于估算进化树分化时间的软件，在进化生物学、分子生物地理学等学科有着广泛的应用，是估算分化时间常用的软件之一。

Feb 17, 2015 · r8s is one of the two principal tools for doing dated analyses; the other one is the Bayesian software package BEAST. Many people, especially religious Bayesians , would probably say that r8s has been made redundant by BEAST.
