Total narrow-sense heritability estimates for real phenotypes under the K_IBD & K_IBD & age & sex & 10 PCs model using (i) GCTA; (ii) GCTA followed byPCA-based rescaling; and (iii) LDAK with an optimal trait-specific parameter α and LD weighting, as well as comparison with (iv) published totalheritability estimates in Europeans and Mexicans.
