Examination of Potential Effect of Different Tag SNP Strategies on Power, When the Causal Variant is Rare (0.01 < MAF < 0.05)
Solid line: Resequencing design; dashed line: tag SNP design, with tags selected using method from [19]; and dotted line: tag SNP design, with all SNPs except the causal SNP as tags.
