| z threshold | Window |
|
SSN |
|---|---|---|---|
| 0.10 | 1 h | (−0.78, −0.74) | (0.20, 0.22) |
| 0.15 | (−0.74, −0.72) | (0.15, 0.15) | |
| 0.25 | (−0.68, −0.65) | (0.08, 0.06) | |
| 2 h | (−0.69, −0.66) | (0.10, 0.09) | |
| 3 h | (−0.71, −0.67) | (0.12, 0.12) |
Notes. The coefficients are calculated for the switchback occurrence rate under different deflection thresholds, background windows, and normalization units. The values in parentheses correspond to normalization per unit time (per hour) and per unit distance (per million kilometers), respectively.
