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.
