Changes in version 0.8.0 (2024-12-02)                  

This is a major update to the package adding additional plotting methods

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 Added plot.vif.ridge() to plot VIFs
vs shrinkage o Added norm.diff = sqrt((b_OLS - b_ridge)^2) as a measure
of shrinkage to precision() o Added plot.precision() for plots of
shrinkage vs. precision o Added best() to display the optimal shrinkage
criteria

                 Changes in version 0.7.1 (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()
