gipsDA: Training DA Models Utilizing 'gips'
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>).
