tidy_vif

Description

Quick and tidy-friendly adaptation of car's 'vif()'. Returns a dataframe with variance inflation, tolerance, and a flag identifying if either is beyond common cut-offs reflecting problematic input variables. Note that VIF is not particularly useful when looking at categorical predictors, and will often report high VIF if any categories with a small sample size exist.

Usage

tidy_vif(mod)

Arguments

mod	Input model to assess for variance inflation among predictors.

Value

Dataframe with model/term metrics.

Examples

## Not run: 

  mtcars |>
    lm(mpg ~ .,
       data = _) |>
    tidy_vif()


## End(Not run)
