Plot ROC AUC Values for Balance Assessment

Creates a visualization of AUC values from weighted ROC analysis. Values near 0.5 indicate good balance.

Usage

plot_roc_auc(
  .data,
  ref_line = TRUE,
  ref_color = "red",
  point_size = 3,
  point_shape = 19
)

Arguments

.data

Output from check_auc().

ref_line

Show reference line at AUC = 0.5? Default is TRUE.

ref_color

Color for reference line. Default is "red".

point_size

Size of the points. Default is 3.

point_shape

Shape of the points. Default is 19 (filled circle).

Value

A ggplot2 object.

Examples

# Compute AUC values
auc_data <- check_auc(
  nhefs_weights,
  qsmk,
  .fitted,
  c(w_ate, w_att)
)

# Create plot
plot_roc_auc(auc_data)
