Figure 1. Power comparison under simulation set 1 when μ = 2.

In the first row, we compare power of the three methods for different values of heritability under the three disease models while sample size is 600 trios and the number of markers selected at the first stage is 10. In the second row, we compare power of the three methods for different numbers of markers selected at the first stage under the three disease models while sample size is 600 trios and heritability is 0.05. In the third row, we compare power of the three methods for different sample sizes under the three disease models while heritability is 0.05 and the number of markers selected at the first stage is 10. In each case, we use 800 genomic markers to control for population stratification in the admixture screening test.
