Row 3 (interpreted like <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0110257#pone-0110257-g006" target="_blank">Figure 6</a>) shows the distribution of the RMSE from the fitted values estimated using RE estimation (red), FE estimation (blue), and WB approach (green). The correlation between the explanatory variable and the residual is set to 0.2. All other simulation input parameters are set to baseline.
