%description
Functions for assessing variable relations and associations prior to
modeling with a Random Forest algorithm (although these are relevant for
any predictive model). Metrics such as partial correlations and variance
inflation factors are tabulated as well as plotted for the user. A
function is available for tuning the main Random Forest hyper-parameter
based on model performance and variable importance metrics. This
grid-search technique provides tables and plots showing the effect of the
main hyper-parameter on each of the assessment metrics. It also returns
each of the evaluated models to the user. The package also provides
superior variable importance plots for individual models. All of the plots
are developed so that the user has the ability to edit and improve further
upon the plots. Derivations and methodology are described in Bladen (2022)
