Inference of demographic histories from autosomal sites. (A) Four simple demographic models fit with $\partial a\partial i$. Each model is parameterized by one or more of an ancestral effective population size (N₀), time of population-size change (τ), change in population size as fraction of initial size (f), and present effective population size (N_e). (B) Observed site frequency spectra by population, with fitted spectra from the four models in panel A. (C) Relative support for each model, quantified by Aikake weight, by population.
