Figure 3

Comparison of correlation estimates r and r t . Each composite plot consists of a joint histogram and the corresponding marginal histograms. Joint probabilities were mapped to grayscale intensities. A: Results for synthetic data. Top row: T=100. Bottom row: T=300. Left and mid column: r vs. ρ and r t vs. ρ, respectively; mean (solid) and mean±STD (dashed) per ρ-bin shown in red. Right column: r t vs. r; Deming regression line (dashed) shown in orange. B: Results for fMRI data (r t vs. r). Top row: Cambridge data set. Bottom row: Pittsburgh data set. Left and mid column: Based on correlation matrices C r and C r t from two individual subjects. Right column: Based on all subject-specific correlation matrices C r and C r t . Deming regression line (dashed) shown in orange.
