Proper L2-penalized maximum likelihood estimators for precision
matrices and supporting functions to employ these estimators in a graphical
modeling setting. For details see van Wieringen & Peeters (2016)
The R-package rags2ridges performs L2-penalized estimation of precison (and covariance) matrices. The package contains proper L2-penalized ML estimators for the precision matrix as well as supporting functions to employ these estimators in a (integrative or meta-analytic) graphical modeling setting. The package has a modular setup and features fast and efficient algorithms.
