Example of the calculated joint probability density p(ω, CNR | s, M) for motor activation data for a neighborhood size s = 5 and cCCA with the maximum constraint. The function was determined using 2D kernel density estimation with a 2D Gaussian kernel. The variables ω and CNR specify the statistic and the contrast-to-noise ratio of the 5-voxel neighborhood, respectively. The threshold to obtain FWE <0.05 is ω ₀ = 6.7.
