Column 1: Gene length sub-group. Column 2: Drop-off rate per bin (rb). Column 3: Drop-off rate per codon (rc). Column 4: RMSE. Column 5: coefficient of determination (R2). Column 6: Standard error estimate (SE). Column 7: Confidence interval 95%. Column 8: P-value resulting from the t-test (null hypothesis: r_b = 0) performed according to Equation (6).
