Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

lr_fit <- lr_workflow %>%
  fit(test)

# Augment the fit object to assess the model
lr_aug <- lr_fit %>%
  ___(test)

lr_aug %>% class_evaluate(truth = Attrition,
                          estimate = .pred_class,
                          .pred_No)
