Simulation Study 1A (autocorrelated markers). On the top row, the X-axis plots the parameter ρ, the autocorrelation correlation coefficient between simulated markers as described in Supplementary Section 4. Estimates of h² using different estimators are plotted along the Y-axis. The value n refers to the number of individuals simulated. The value M is the total number of markers simulated, where half of the markers are causal, set in an alternating fashion, as described in Simulation Strategy. We consider (i) $n=1,000,m=100$ (ii) $n=200,m=500$, (iii) $n=200,m=1,500$, and (iv) $n=2,000,m=500$. Five hundred data sets were simulated for each condition. A horizontal line is shown at $h^2=.8$, the simulated truth. On the bottom row, the X-axis is the parameter ρ, and the MSE of each of the estimators is plotted on the Y-axis.
