In kerndwd: Distance Weighted Discrimination (DWD) and Kernel Methods

Description Details Author(s) References

Extremely novel efficient procedures for solving linear generalized DWD and kernel generalized DWD in reproducing kernel Hilbert spaces for classification. The algorithm is based on the majorization-minimization (MM) principle to compute the entire solution path at a given fine grid of regularization parameters.

Suppose x is predictor and y is a binary response. The package computes the entire solution path over a grid of lambda values.

The main functions of the package kerndwd include:
kerndwd
cv.kerndwd
tunedwd
predict.kerndwd
plot.kerndwd
plot.cv.kerndwd
