## genridge 0.8.0 (2024-11-30)

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

## genridge 0.7.1 (2024-11-07)

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()`
