Figure 7. The relation between pairwise couplings and pairwise correlations.

Figure 7

This figure shows that there is a simple relation between Inline graphic and Inline graphic, but not between Inline graphic and Inline graphic. (A, C, E) Inline graphic versus the normalized coefficients, Inline graphic (blue points), along with the predicted relationship, via Eq. (18b) (black line). (B, D, F) Inline graphic versus the Pearson correlation coefficients, Inline graphic, Eq. (26) (blue points). The three columns correspond exactly to the columns in Fig. 5 from left to right; that is, Inline graphic for (A, B), Inline graphic for (C, D), and Inline graphic for (E, F). The prediction in the top row (black line) matches the data well, even in the rightmost column.
