Fig. 3.

(a) Number of SNPs with P-value < 0.05 versus number of valid samples over 10 000 SNPs, where the number of SNPs become stable when there are more than 400 valid samples. (b) Average time cost to securely generate a valid sample versus different number of cores using the KD dataset with 15 records. The time cost is for the computation of 180 SNPs in parallel based on the scenario (ii) in Section 2.3, where a total of 1440 samples were drawn for each SNPs with an acceptance rate of 17.397% (Color version of this figure is available at Bioinformatics online.)
