Cost-effectiveness plane and CEAC curve — plot_cost

Plots the cost-effectiveness plane (delta cost vs. delta outcome) for a set of scenarios and, optionally, a cost-effectiveness acceptability curve (CEAC) across willingness-to-pay thresholds.

Usage

plot_cost_effectiveness(
  data,
  reference,
  scenarios,
  outcome_col = "completion_rate",
  cost_col = "cost",
  wtp = seq(0, 2e+05, length.out = 40),
  show_ceac = FALSE
)

Arguments

data: A dynasimR_data object or summary tibble.
reference: Character. Scenario ID treated as the comparator.
scenarios: Character vector. Scenarios to evaluate against reference.
outcome_col: Character. Outcome column. Default "completion_rate".
cost_col: Character. Cost column. Default "cost".
wtp: Numeric vector. Willingness-to-pay thresholds for CEAC. Default seq(0, 2e5, length.out = 40).
show_ceac: Logical. If TRUE, return a CEAC plot instead of the CE plane. Default FALSE.

Value

A ggplot2 object.
