Package: ridgregextra Type: Package Title: Ridge Regression Parameter Estimation Version: 0.1.1 Authors@R: c( person("Filiz", "Karadag", , "filiz.karadag@ege.edu.tr", role = c("aut"), comment = c(ORCID = "0000-0002-0116-7772")), person("Hakan Savas", "Sazak", , "hakan.savas.sazak@ege.edu.tr", role = c("aut"), comment = c(ORCID = "0000-0001-6123-1214")), person("Olgun", "Aydin", , "olgun.aydin@pg.edu.pl", role = c("cre"), comment = c(ORCID = "0000-0002-7090-0931"))) Description: It is a package that provides alternative approach for finding optimum parameters of ridge regression. This package focuses on finding the ridge parameter value k which makes the variance inflation factors closest to 1, while keeping them above 1 as addressed by Michael Kutner, Christopher Nachtsheim, John Neter, William Li (2004, ISBN:978-0073108742). Moreover, the package offers end-to-end functionality to find optimum k value and presents the detailed ridge regression results. Finally it shows three sets of graphs consisting k versus variance inflation factors, regression coefficients and standard errors of them.
