How Energy Distance Detects Distribution Shifts Between Training and Test Sets

Energy Distance is a statistical metric that quantifies the separation between two probability distributions by comparing cross‑distribution and within‑distribution Euclidean distances, enabling detection of data drift, covariate shift, and other multivariate distribution changes, especially when combined with permutation testing for statistical significance.
