| SAA | −22.3 ± 19.2 | 1.69 ± 0.59 | 0.91 ± 0.16 | −0.87 ± 12.3 | 1.01 ± 0.32 | 0.91 ± 0.17 |
| SIER | −17.8 ± 42.9 | 0.85 ± 0.75 | 0.54 ± 0.26 | 11.65 ± 11.9 | 1.23 ± 0.32 | 0.85 ± 0.18 |
| EFE | 10.6 ± 10.7 | 0.86 ± 0.15 | 0.94 ± 0.04 | 7.18 ± 6.6 | 0.97 ± 0.18 | 0.96 ± 0.05 |
aExpected (ideal) values of the LFM parameters are A = 0, B = 1, and R 2 = 1.
