Bayesian phylogeny
MrBayes is a free software tool that performs Bayesian inference of phylogeny. It was originally written by John P. Huelsenbeck and Frederik Ronquist in 2001. As Bayesian methods increased in popularity, MrBayes became one of the software of choice for many molecular phylogeneticists. It is offered for … See more Bayesian inference of phylogeny combines the information in the prior and in the data likelihood to create the so-called posterior probability of trees, which is the probability that the tree is correct given the data, the prior and the … See more There are many approaches to reconstructing phylogenetic trees, each with advantages and disadvantages, and there is no … See more Bayesian Inference has extensively been used by molecular phylogeneticists for a wide number of applications. Some of these include: • Inference of phylogenies. • Inference and evaluation of uncertainty of phylogenies. See more Bayesian inference refers to a probabilistic method developed by Reverend Thomas Bayes based on Bayes' theorem. Published posthumously in 1763 it was the first expression of … See more • Bootstrap values vs posterior probabilities. It has been observed that bootstrap support values, calculated under parsimony or maximum likelihood, tend to be lower than the posterior probabilities obtained by Bayesian inference.
