Estimates (estimated standard errors) of proportion of variance explained () and of prediction R-squared of phenotypes in validation datasets, <i>R²</i> (TST).

FHS = Framingham Heart Study, GEN = GENEVA, RAND: in this scenario causal and marker loci were drawn from the same distribution, Low-MAF: in this scenario marker loci were drawn at random and causal loci were drawn over-sampling loci with low minor allele frequency, TST = Testing data set. (1): average (over 30 MC replicates) estimated posterior mean of the ratio of genomic variance over the sum of genomic and residual variance; (2): average prediction R2 (phenotypes) over 30 training (N = 5,300)-testing (N = 500) partitions.
