error rates than fastPHASE (black) and BEAGLE (green). The IMPUTE v2 run with k = 40 (solid red line) attained similar accuracy to IMPUTE v1 at stringent calling thresholds (Figure 3B), although IMPUTE v2 gained a slight advantage at more lenient thresholds (Figure 3C). The IMPUTE v2 run with k = 80 (dotted red line) showed a small but consistent improvement over both IMPUTE v1 and the other IMPUTE v2 run.
