In BCEA: Bayesian Cost Effectiveness Analysis

Cost-effectiveness acceptability frontier

In addition to the CEAC, we can also visualise the uncertainty in the decision-making process using the Cost-Effectiveness Acceptability Frontier (CEAF). The frontier is defined as the maximum value of the probability of cost-effectiveness among all comparators. It is an indication of the uncertainty associated with choosing the cost effective intervention. In other terms, higher frontier values correspond to lower decision uncertainty.

n.ints <- m$n_comparators

if (n.ints == 2) {
  graph <- "base"
  pos <- c(1, 1)
} else {
  graph <- "ggplot2"
  pos <- TRUE
}
