Collinearity / VIF check via performance — morie_performance_check

Thin extender over performance::check_collinearity for the variance-inflation-factor diagnostic.

Usage

morie_performance_check_collinearity(model, ...)

Arguments

model: A fitted model object supported by performance.
...: Further arguments forwarded to performance::check_collinearity (e.g. ci, verbose).

Value

A list with $method = "performance::check_collinearity" and $raw (the upstream VIF data frame).

Examples

if (requireNamespace("performance", quietly = TRUE)) {
  set.seed(1)
  df <- data.frame(y = rnorm(50), x1 = rnorm(50), x2 = rnorm(50))
  morie_performance_check_collinearity(stats::lm(y ~ x1 + x2, df))
