Figure 6: fMRI: t value distributions of comparing voxel-wise accuracy with overall accuracy (for exemplary j × n combinations and scales).
From: On the estimation of brain signal entropy from sparse neuroimaging data
Regardless of the number of data segments, data points per segment, and time scale, deviation of the voxel-wise accuracy from overall accuracy were effectively zero-centered, with tighter and more symmetric distributions at higher data densities (scale 1 vs. higher scales; lower vs. higher number of data points per segment).
