## Correlation Structures
|
| 1392 |
+
The dataset features 23 distinct correlation structures representing different combinations of strong positive, negligible, and strong negative correlations between three time series variates. These structures are based on meaningful thresholds for strong negative ([-1,-0.7]), negligible ([-0.2,0.2]), and strong positive ([0.7,1]) correlations.
