| Males | y = 21.347 + 0.488×E1−0.412×C1+0.360×F5+0.125×E7+0.320×E5 | 0.96 | 0.96 | 3.45 | 2.64 |
| Combined | y = 24.260 + 0.348×F1−0.463×C1+0.188×E3+0.151×E1+0.088×T4+0.315×E2−0.260×F4+0.222×F2+0.054×E7+0.125×T5 | 0.95 | 0.94 | 3.89 | 2.97 |
R2, coefficient of determination/goodness-of-fit; Adjusted R2, adjusted coefficient of determination; RMSE, root mean square error; MAD, median absolute deviation.
