Actual power of the ssPCC proposed testing procedure based on a Z-test (see the section ssPCC: Single Sample Network Based on Pearson’s Correlation and eq 12) as a function of the effect size defined in the section Power of the ssPCC Test using the Simulation Scheme 1. The nine panels (A–I) correspond to the different correlation ρ₀ of the ssPCC reference network (PCC_n, see eq 14): the values are −0.9, −0.7, −0.5, −0.3, 0, 0.3, 0.5, 0.7, and 0.9, respectively. For each value of ρ₀, we let ρ_q (see eq 16) to vary in the range [0:1] with increments of 0.1. The effect size is defined as ρ_q – ρ₀, so that for each ρ₀ there are 11 effect size values, indicated on the y-axis of the bar plots. Results are shown for sample size n = 1. The actual power is calculated over 1000 tests. The vertical dashed red lines indicate the 5% level.
