Effect of unknown patient-level predictor on model prediction accuracy. Plots show the density of values for relative improvement in MAE across 1,000 simulations, with horizontal bars representing the mean value, for different values of β 2, which controls the size of the effect of the unknown patient-level predictor, X 2ij , to the outcome, Y ij . Note that the relative contribution of X 2ij to the total variance in Y ij , compared to X 1ij , is equal to β 22 . All other parameters are fixed at their base values
