genridge 0.7.2 (2024-11-15)
o Fleshed out and installed plot.precision() o Illustrate plot.precision() in README.Rmd o Added diab data, diabetes from CASI o Fixed documentation for plot.ridge() so that plot.pcaridge() is documented explicitly. o ’vif.ridge()now returns a "vif.ridge" object list to prepare for a plot method. o Addedplot.vif.ridge()to plot VIFs vs shrinkage o Addednorm.diff= sqrt((b_OLS - b_ridge)^2) as a measure of shrinkage toprecision()o Addedplot.precision()for plots of shrinkage vs. precision o Addedbest()` to display the optimal shrinkage criteria
genridge 0.7.1 (2024-11-07)
CRAN release: 2024-11-13
o Added links to gentalk.pdf o Improved README and fixed some examples o precision() result gains a class “precision” in preparation for a plot method o Implemented plot.precision() for plots shrinkage vs. variance, using various criteria o Fixed warning from ridge() related to contrasts o ridge() now collects the optimal criteria in a named list, which can be added in plot.precision()
