randomForestVIP - Tune Random Forests Based on Variable Importance and Plot
Results
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)
