Plot a Bayesian (brms) choice-based discounting model — plot.beezdiscounting_choice

Visualize a fitted fit_dd_choice_brms() model. type = "population" (default) draws the posterior implied discount curve with a credible band; type = "individual" adds per-subject (posterior-median) curves; type = "parameters" shows the posterior subject-k caterpillar; and type = "calibration" plots observed choice proportion against fitted P(choose LL), binned by fitted probability.

Usage

# S3 method for class 'beezdiscounting_choice_brms'
plot(
  x,
  type = c("population", "individual", "calibration", "parameters"),
  ids = NULL,
  at = NULL,
  n_points = 200,
  x_trans = c("log10", "linear"),
  show_observed = TRUE,
  ...
)

Arguments

x: A beezdiscounting_choice_brms object.
type: One of "population", "individual", "calibration", "parameters".
ids: Optional subset of subject ids for type = "individual".
at: Optional named list conditioning the population curve on factor levels / covariate values.
n_points: Number of delay points in the curve grid.
x_trans: Delay-axis scale: "log10" (default) or "linear".
show_observed: Unused for the implied discount curve.
...: Unused.

Value

A ggplot2::ggplot object.
