Relationships between the Observer Freeze Duration measure and the Kinect, Load Platform and KLT estimates of freeze duration.
| Measure | n | Corr. Coef. (p-value) | Coefficient estimate (with SE) | Wald Χ2 (p-value) |
|---|---|---|---|---|
| Kinect Acceleration | 282 | 0.837 (<0.001) | 0.876 (0.030) | 381.299 (<0.001) |
| Kinect Speed | 282 | 0.833 (<0.001) | 0.867 (0.027) | 422.209 (<0.001) |
| Load Platform | 283 | 0.784 (<0.001) | 1.030 (0.0.34) | 397.375 (<0.001) |
| KLT Acceleration | 283 | 0.771 (<0.001) | 0.908 (0.034) | 351.285 (<0.001) |
| KLT Speed | 283 | 0.821 (<0.001) | 0.848 (0.027) | 412.752 (<0.001) |
Correlation Coefficients and associated p-values were calculated using a Spearman Rank Correlation. The Coefficient Estimate, related Standard Error, Wald statistic and associated p-value were from the multilevel models.
