Changes in version 0.3.1 (2022-05-20) o Bug fix: incorrectly placed bracket on the C++ part of the ridgeGGMmixture-function assigned to its proper spot. o Extra input check in the ridgePgen.kCV.groups-function. o Citations updated. o To fix a note of CRAN's check results the rags2ridges- and ragt2ridges-packages are added to Suggests in the Description-file. o Input checks are now performed by means the inherits-function instead of the class-function. Changes in version 0.3.0 (2022-01-08) o Functionality of the ridgeGLM and optPenaltyGLM.kCVauto expanded. Among others, unpenalized covariates may now be supplied and a generalized penalty matrix provided. o Bug fix: correct stopping criterion for the IRLS algorithm of the penalized ridge logistic regression estimator. o Citations updated. Changes in version 0.2.1 (2021-04-19) o Faster implementation of the functions for target and multi-targeted ridge estimation of the GLM offered. Changes in version 0.2.0 (2021-02-09) o Reference added to the Description-file. o Functions for target and multi-targeted ridge estimation of the GLM added. Changes in version 0.1.1 (2021-01-11) o Corrected DOIs in the Description field. Changes in version 0.1.0 (2020-05-18) o Restructuring of R and C++ files into modules. o Novel module added. o Some layout polish in the manual. Changes in version 0.0.4 (2019-12-16) o Modification of C++ code related to the ridgePrepEdiag- and optPenaltyPrepEdiag-functions. In case of an unbalanced design the initialization of EM algorithm no longer yields negative definite precisiom matrices. Changes in version 0.0.3 (2019-12-05) o Modification of input checks to meet CRAN's best practice. o Removed an accidently inserted section in the manual of the optPenaltyGGMmixture.kCVauto-function. Changes in version 0.0.2 (2019-11-13) o The unnecessary dependency on the rags2ridges-packages has been removed. Changes in version 0.0.1 (2019-11-01) o Release of the Urfassung.
