Abstract

We describe a new p-parameter generalized ridge-regression shrinkage-pattern recently implemented in the RXshrink CRAN R-package. The five distinct types of ridge TRACE displays discussed and illustrated here provide invaluable data-analytic insights and improved self-confidence to researchers and data scientists fitting linear models to ill-conditioned datasets.

Comments

Considerable text overlap with arXiv:2103.05161 plus use of a less-efficient and more complicated shrinkage path
