%description
Efficient framework for ridge redundancy analysis (rrda), tailored for
high-dimensional omics datasets where the number of predictors exceeds the
number of samples. The method leverages Singular Value Decomposition (SVD)
to avoid direct inversion of the covariance matrix, enhancing scalability
and performance. It also introduces a memory-efficient storage strategy
for coefficient matrices, enabling practical use in large-scale
applications. The package supports cross-validation for selecting
regularization parameters and reduced-rank dimensions, making it a robust
and flexible tool for multivariate analysis in omics research. Please
refer to our article (Yoshioka et al., 2025) for more details.
