%description
Implements the Multi-view Aggregated Two-Sample (MATES) test, a powerful
nonparametric method for testing equality of two multivariate
distributions. The method constructs multiple graph-based statistics from
various perspectives (views) including different distance metrics, graph
types (nearest neighbor graphs, minimum spanning trees, and robust nearest
neighbor graphs), and weighting schemes. These statistics are then
aggregated through a quadratic form to achieve improved statistical power.
The package provides both asymptotic closed-form inference and
permutation-based testing procedures. For methodological details, see Cai
and others (2026+) <doi:10.48550/arXiv.2412.16684>.
