  1. Simulation parameters: H = heritability, K = prevalence, RR = relative risk for each risk allele. The number of simulated disease loci is shown. For the one, three, five, ten and 20 top scoring loci for each of the 25 simulated genome scans, we show how many coincided with true disease loci (and their percentages), as well as their average non-parametric linkage (NPL) score.
