Compare profile and Wald confidence intervals

plot_profile_vs_wald(x, parameter = NULL, ci_level = 0.95,
  n_points = 200, ...)

Arguments

x: A likelihood_function object
parameter: Name of the parameter to plot. If NULL, uses the first parameter.
ci_level: Confidence level (default: 0.95)
n_points: Number of parameter values for profile likelihood evaluation
...: Additional arguments passed to plot

Value

Invisibly returns a list with elements profile and wald containing the respective confidence interval bounds

Details

Plots the profile likelihood with both profile-based and Wald (normal approximation) confidence interval bounds overlaid for comparison. Differences between the two methods indicate departures from normality or asymmetry in the likelihood.
