%description
Provides resistant alternatives to the standard Procrustes analysis for
comparing multivariate datasets, including seven resistant Procrustean
methods and their associated permutation tests, as well as the standard
Procrustes analysis and its permutation tests. Methods are based on Tang
and Jackson (2026) "Improving and evaluating resistant alternatives to
Procrustes analysis for multivariate dataset matching"
<doi:10.1002/env.70073>.
