Data gij were simulated from the binomial model (Equation 1) using known (Q, F). F was taken as the ancestral allele frequencies corresponding to the HapMap CHB, CEU, and YRI samples; the qi were sampled i.i.d. (independent and identically distributed) according to the Dirichlet distributions indicated. The figure indicates the points (qi1, qi2). Both ADMIXTURE and structure closely recovered the true (Q, F). FRAPPE'S estimates were less accurate.
