%description
Implements the whitening methods (ZCA, PCA, Cholesky, ZCA-cor, and
PCA-cor) discussed in Kessy, Lewin, and Strimmer (2018) "Optimal whitening
and decorrelation", <doi:10.1080/00031305.2016.1277159>, as well as the
whitening approach to canonical correlation analysis allowing negative
canonical correlations described in Jendoubi and Strimmer (2019) "A
whitening approach to probabilistic canonical correlation analysis for
omics data integration", <doi:10.1186/s12859-018-2572-9>. The package also
offers functions to simulate random orthogonal matrices, compute
(correlation) loadings and explained variation. It also contains four
example data sets (extended UCI wine data, TCGA LUSC data, nutrimouse
data, extended pitprops data).
