...Admixture graph fitting has some similarities to the TreeMix method of Pickrell and Pritchard (2012) but differs in that TreeMix allows users to automatically explore the space of possible models and to find the one that best fits the data (our method does not), while our method provides a rigorous…...

...A natural extension of this hierarchical prior would be to allow for a full locus-independent variance–covariance matrix (Pickrell and Pritchard 2012)....

...e., the mean across all SNPs of X ik (1 X ik )). A natural estimator of B i is then: B i = h i 4N i (4) where h i is an unbiased estimate of the heterozygosity in population i averaged over all SNPs [Nei, 1978]: h i = 1 n Xn k =1 n ik (2 N i n ik ) N i(2 N i 1) : (5) As derived in the main text, the sample covariance of populations i and j, W ij , is: W ij = V ij 1 m Xm k =1 V ik 1 m Xm k =1 V jk + 1 m 2 X...

...Graph-based models are of growing interest in phylogenetics [45,46], but have been rarely used in population genetics (with some exceptions [37,40,47])....
