A Studentized Spherical Harmonics–Based Nonparametric Two-Sample Test for Compositional and Directional Data
ICML 2026poster
Compositional data analysis has gained increasing attention due to the widespread occurrence of simplex-valued data, including microbiome data. However, existing kernel or distance-based nonparametric two-sample tests are often designed for Euclidean data and rely on square-root or log-transformatio…
