Power of the ln RV test statistic in relation to the variance of ln RV across loci

Variance in ln RV
r2.71.71.5
0.010.760.840.90
0.10.350.420.48
• The power is expressed as the fraction of simulations that identified a locus linked to a selective sweep as a significant (P < 0.05) outlier. r, fraction to which variability was reduced due to linkage to a selected site; the variance in ln RV was determined over 1000 replicate simulations of 99 microsatellite loci. One locus was assumed to be linked to a selected site. Different sample sizes in the computer simulations were used to obtain the differences in ln RV.
