%description
Provides a comprehensive and automated workflow for managing
multicollinearity in data frames with numeric and/or categorical
variables. The package integrates five robust methods into a single
function: (1) target encoding of categorical variables based on response
values (Micci-Barreca, 2001 (Micci-Barreca, D. 2001
<doi:10.1145/507533.507538>); (2) automated feature prioritization to
preserve key predictors during filtering; (3 and 4) pairwise correlation
and VIF filtering across all variable types (numeric–numeric,
numeric–categorical, and categorical–categorical); (5) adaptive
correlation and VIF thresholds. Together, these methods enable a reliable
multicollinearity management in most use cases while maintaining model
integrity. The package also supports parallel processing and progress
tracking via the packages 'future' and 'progressr', and provides seamless
integration with the 'tidymodels' ecosystem through a dedicated recipe
step.
