Figure 8 : A comparison of SPA and GPS prediction accuracy for continental regions.

Figure 8

The mean longitude and latitude for each population were calculated by averaging individual spatial assignments (N=596). After assigning populations to continental regions, the mean and s.d. were calculated based on the predicted coordinates for each region. Dashed lines mark s.d. (a) SPA prediction accuracy for continental regions obtained from Yang et al.12 results (their supplementary Table 112). The mean coordinates are marked with a triangle (expected) and square (Predicted by SPA). (b) Comparing the results for worldwide populations analysed here for SPA (square), GPS (circle) and for the real coordinates (triangle).
