## Figure 10.
Gap Statistic Across Varying Cluster Sizes for HGDP Africans and NECS. The graph plots the mean gap statistic (see Methods) at each cluster size. The gap
statistic for the HGDP Africans steadily increases to 21 clusters at which point the
statistic cannot be computed due to singleton clusters. For the NECS, the statistic
again increases with an increasing cluster size and does not reach a point after which
the statistic continuously decreases. In both situations choosing an optimal cluster
size is not obvious.
