Table 2 Performances of all 9 regression-based Abs_CO prediction methods

The correlation coefficients, the average percent correct values, and the standard deviations of the percent correct values for all 9 regression-based Abs_CO prediction methods. The first set of results (rows 3–5) are for Method 1 in which the percentage of residues in alpha helices, p(α), and beta strands, p(β), are used as two factors. In particular, the F3-LR regression formula is Abs_CO = -6.8968p(α) + 7.6216p(β) + 0.0612L + 8.0397. The second set of results (rows 6–8) are for Method 2 in which the numbers of residues in alpha helices, q(α), and beta strands, q(β), are used as two factors. In particular, the F3-LR regression formula is Abs_CO = -0.0591q(α) + 0.0789L + 8.3774. The third set of results (rows 9–11) are for Method 3 in which the numbers of alpha helices, n(α), and beta strands, n(β), are used as two factors. In particular, the F3-LR regression formula is Abs_CO = -0.4184n(α) + 0.1992n(β) + 0.0611L + 8.647.
