BEAST 2 is an open source software tool and platform designed for Markov chain Monte Carlo (MCMC)-based Bayesian inference of phylogenetic trees and associated population-level (i.e. phylodynamic) parameters from (primarily) genetic sequence data under a large variety of specific models.
💡 BEAST 2 can be used to quantify epidemiological dynamics in real-time based on viral genomes and confirmed case data.
