Independently, unaware of Bayes work, Pierre-Simon Laplace developed Bayes' theorem in 1774.
Bayesian inference was widely used until 1900s when there was a shift to frequentist inference, mainly due to computational limitations.
This tutorial introduces the BEAST software for Bayesian evolutionary analysis through a simple tutorial.
The second step is to actually run BEAST using the input file generated by BEAUTi, which contains the data, model and analysis settings.
The final step is to explore the output of BEAST in order to diagnose problems and to summarize the results.
This is done using the program BEAUti (which stands for Bayesian Evolutionary Analysis Utility).
This is a user-friendly program for setting the evolutionary model and options for the MCMC analysis.
