Sensitivity of the (solid line) and correlation (dashed line) to the choice of the regularization coefficient.
Simulations come from Experiment 2 with a true signal strength of s = 0.2 and a noise variance of 1. For this combination the optimal regularization coefficient is (dashed vertical line). The correlation criterion is generally robust against non-optimal choice of regularization coefficient.
