Figure 2.

Ten-fold cross-validation of K = 2 through K = 10 clusters from ADMIXTURE analysis with 10 randomly selected subsets of n = 175 individuals from the Ashkenazi Jewish (AJ) cohort, combined with HGDP subjects as indicated in Figure 1. The x-axis represents the number of clusters (K) in the model and the y-axis represents cross-validation score (lower scores represent better fit of the model to the data). Ten different colors represent different runs.
