MrBayes uses Markov chain Monte Carlo (MCMC) methods to estimate the posterior distribution of model parameters. + +----- + +**Model Definitions** + +Models are defined by the following MrBayes options:: + + GRT: lset nst=6; + SYM: lset nst=6; prset statefreqpr=fixed(equal); + HKY: lset nst=2; + K2P: lset nst=2; prset statefreqpr=fixed(equal); + F81: lset nst=1; + JC: lset nst=1; prset statefreqpr=fixed(equal); + Mixed: lset nst=mixed; + +Each model makes different assumptions about nucelotide substitution rates and state frequencies. + +The mixed model performs Markov chain sampling over the space of all possible reversible substitution models, by grouping the six rates in various combinations. + +----- + +.. class:: infomark + +**TIP** + +See the manual_ or the `command reference`_ for more information. + +.. _manual: http://mrbayes.sourceforge.net/manual.php +.. _command reference: http://mrbayes.sourceforge.net/commref_mb3.2.pdf + + + +
