Table 2. SNP population-based method: Mean population distance within clusters compared to mean distance among clusters.
| Mean distance | Squared euclidean | Squared chord | Manhattan city-blocks |
|---|---|---|---|
| Within EA cluster | 0.0185 | 0.0362 | 0.0869 |
| Within WM cluster | 0.0186 | 0.0244 | 0.1186 |
| Within MM cluster | 0.0142 | 0.0202 | 0.1223 |
| Within EM cluster | 0.0184 | 0.0238 | 0.1428 |
| Mean within clusters | 0.0178 | 0.0253 | 0.1269 |
| Mean between clusters | 0.0883 | 0.1053 | 0.2694 |
| Significance | p < 0.001 | p < 0.001 | p < 0.001 |
