About Migrate

Migrate estimates effective population sizes and past migration rates between two or n populations assuming a migration matrix model with asymmetric migration rates and different subpopulation sizes. The n-population migrate can use: sequence data using Felsenstein's extension to the Kimura 2-parameter model, microsatellite data using a stepwise mutation model or a brownian motion mutation model, and electrophoretic data using an infinite allele model. The output can contain: Estimates of all migration rates and all population sizes, assuming constant mutation rates among loci or a gamma distributed mutation rate among loci. Profile likelihood tables, Percentiles, Likelihood-ratio tests, and simple plots of the log-likelihood surfaces for all populations and all loci.
