# LAMARC - Likelihood Analysis with Metropolis Algorithm using Random Coalescence

This documentation covers use of the program LAMARC, which can estimate population sizes, migration rates, growth rates, and recombination rate using a Metropolis-Hastings Monte Carlo Markov Chain algorithm. LAMARC's 'sister program' is MIGRATE, with which it shares history, algorithms, and some code base, but which is now being maintained exclusively by Peter Beerli at Florida State University.
