%description
Extends classical linear and quadratic discriminant analysis by
incorporating permutation-group symmetries into covariance matrix
estimation. Methods based on the 'gips' framework identify and impose
permutation structures that regularize covariance estimates and improve
stability and interpretability for symmetric or exchangeable features. The
package provides pooled and class-specific covariance models, including
multi-class variants with shared or independently estimated symmetry
structures. The underlying methodology is described by Graczyk et al.
(2022) <doi:10.1214/22-AOS2174> and Chojecki, Morgen, and Kołodziejek
(2025) <doi:10.18637/jss.v112.i07>.
