Supplementary Figure 7

Simulation results with confounding cryptic relatedness. The contribution of the additive genetic term U in a typical MPMM is a2; each row increases the contribution of the contaminating shared environment, c2, to the overall heritability, here defined as h2 = a2 + c2. The first row uses c2 = 0.1a2; the second uses c2 = 0.3a2; and the last uses c2 = a2. Five percent of phenotype values were held out, and the correlation between the true and imputed values is plotted on the y axis for each method. The dotted lines show the results from Figure 1 for reference.
