Association analysis power curve for individual genotyping versus pooled allelotyping. Individual genotyping: red dashed lines. Pooled allelotyping with 1% to 5% allele frequency estimation error: blue solid lines. Power is defined as the percent of simulations where disease associated loci had association test p-values more significant than (p-value < 0.05). Results are the average of 100 simulations at each of the relative risk levels listed on the X-axis.
