The package leverages methodology\nfrom the 'gips' framework to identify and impose permutation\nstructures that act as a form of regularization, improving\nstability and interpretability in settings with symmetric or\nexchangeable features. Several discriminant analysis variants\nare provided, including pooled and class-specific covariance\nmodels, as well as multi-class extensions with shared or\nindependent symmetry structures.
