Plot permutation-based T-statistics with observed values and p-values — plot_null

Plots null distributions of T-statistics from perm_interaction_effect(). Adds dashed lines for observed T-statistics, optional normal fit overlay, and optional density overlay.

Usage

plot_null_distribution(
  data,
  features = NULL,
  p_normal = TRUE,
  p_empirical = TRUE,
  show_normal = TRUE,
  show_empirical = TRUE,
  bins = 50,
  title = NULL,
  point_size = 0.5
)

Arguments

data: A list from perm_interaction_effect(), must include T_null and summary_stats.
features: Character vector of features to plot. Defaults to first 9 if NULL.
show_normal: Logical. Overlay fitted normal curve? (default TRUE)
show_empirical: Logical. Overlay empirical density curve? (default TRUE)
bins: Integer number of histogram bins (default 50)
title: Optional plot title.
point_size: Numeric value controlling point/label size (currently not used in plotting directly).
show_param: Logical. Show parametric p-values? (default TRUE)
show_emp: Logical. Show empirical p-values? (default TRUE)

Value

A ggplot2 object.
