⚠️There's a newer version (0.7.0) of this package.Take me there.
genridge (version 0.6-3)
Generalized ridge trace plots for ridge regression
Description
The genridge package introduces generalizations of the
standard univariate ridge trace plot used in ridge regression
and related methods. These graphical methods show both bias
(actually, shrinkage) and precision, by plotting the covariance
ellipsoids of the estimated coefficients, rather than just the
estimates themselves. 2D and 3D plotting methods are provided,
both in the space of the predictor variables and in the
transformed space of the PCA/SVD of the predictors.
