Estimated regression coefficients from robust regression (M-estimation and MM-estimation), corresponding t-values and approximate p-values for OFC.
| Regression coefficient M-estimation in 10−7 | Regression coefficient MM-estimation in 10−7 | t-value (p-value) M-estimation | t-value (p-value) MM-estimation | |
|---|---|---|---|---|
| alpha 2 | 6.05 | 4.33 | 2.18 (p = 0.0357) | 1.88 (p = 0.0683) |
| beta 3 | 74.10 | 45.00 | 2.76 (p = 0.0088) | 1.93 (p = 0.0603) |
| theta | 3.46 | 2.32 | 2.19 (p = 0.0344) | 1.73 (p = 0.0912) |
| delta | 43.10 | 16.70 | 2.18 (p = 0.0351) | 0.92 (p = 0.3607) |
| alpha 1 | 1.67 | 0.505 | 1.94 (p = 0.0592) | 0.73 (p = 0.4717) |
| beta 1 | 3.27 | 3.04 | 1.99 (p = 0.0539) | 1.81 (p = 0.0784) |
T-values are computed as t = estimate/SE(estimate) and p-values are obtained using the Wald test.frequency band.
