Asymptotic Distribution-Free Change-Point Detection via a New Ranking Scheme (RING) // Rank-based, asymptotic distribution- free change-point detection for modern (high-dimensional, non- Euclidean) data, based on the graph-induced ranking scheme of Zhou and Chen (2025) doi:10.1109/TIT.2025.3575858. Given a rank matrix built from a pairwise similarity, the method scans for a single change-point or a changed interval using three statistics (weighted 'WR', max-type 'MR', and generalized 'TR') and returns analytic distribution-free p-value approximations (with an optional skewness correction) as well as optional permutation p-values.
