%description
Extends classical linear and quadratic discriminant analysis by
incorporating permutation group symmetries into covariance matrix
estimation. The package leverages methodology from the 'gips' framework to
identify and impose permutation structures that act as a form of
regularization, improving stability and interpretability in settings with
symmetric or exchangeable features. Several discriminant analysis variants
are provided, including pooled and class-specific covariance models, as
well as multi-class extensions with shared or independent symmetry
structures. For more details about 'gips' methodology see and Graczyk et
al. (2022) <doi:10.1214/22-AOS2174> and Chojecki, Morgen, Kołodziejek
(2025, <doi:10.18637/jss.v112.i07>).
