mrbayes是一种贝叶斯估计的系统发育。贝叶斯推理的系统发育的基础上的数量称为后验概率分布是概率树,树的条件的观察。空调是使用贝叶斯定理。后验概率分布是不可能计算分析;相反,mrbayes使用模拟技术被称为马尔可夫链蒙特卡洛(或方法)近似的后验概率树。
MrBayes is a program for the Bayesian estimation of phylogeny. Bayesian inference of phylogeny is based upon a quantity called the posterior probability distribution of trees, which is the probability of a tree conditioned on the observations. The conditioning is accomplished using Bayes's theorem. The posterior probability distribution of trees is impossible to calculate analytically; instead, MrBayes uses a simulation technique called Markov chain Monte Carlo (or MCMC) to approximate the posterior probabilities of trees.
