%description
Effortless multicollinearity management in data frames with both numeric
and categorical variables for statistical and machine learning
applications. The package simplifies multicollinearity analysis by
combining four robust methods: 1) target encoding for categorical
variables (Micci-Barreca, D. 2001 <doi:10.1145/507533.507538>); 2)
automated feature prioritization to prevent key variable loss during
filtering; 3) pairwise correlation for all variable combinations
(numeric-numeric, numeric-categorical, categorical-categorical); and 4)
fast computation of variance inflation factors.
