Distance Metrics

Interval distance functions for comparing interval-valued observations.

idist(): Compute interval distance matrix
idist_euclidean(): Interval Euclidean distance

idist_ichino_yaguchi(): Ichino-Yaguchi dissimilarity for intervals
idist_wasserstein(): L2-Wasserstein (Mallows) distance for intervals

Quality Assessment

Co-ranking indices, permutation tests, and K-profiles.

coranking_indices(): Compute co-ranking quality and behavior indices
