Plot influence diagnostics

Usage

tl_plot_influence(
  model,
  plot_type = "cook",
  threshold_cook = NULL,
  threshold_leverage = NULL,
  threshold_dffits = NULL,
  n_labels = 3,
  label_size = 3
)

Arguments

model: A tidylearn model object
plot_type: Type of influence plot: "cook", "leverage", "index"
threshold_cook: Cook's distance threshold (default: 4/n)
threshold_leverage: Leverage threshold (default: 2*(p+1)/n)
threshold_dffits: DFFITS threshold (default: 2*sqrt((p+1)/n))
n_labels: Number of points to label (default: 3)
label_size: Text size for labels (default: 3)

Value

A ggplot object.

Examples

# \donttest{
model <- tl_model(mtcars, mpg ~ wt + hp, method = "linear")
tl_plot_influence(model, plot_type = "cook")
