multi.ce {BCEA}

Cost-effectiveness Analysis With Multiple Comparison

Description

Computes and plots the probability that each of the n_int interventions being analysed is the most cost-effective and the cost-effectiveness acceptability frontier.

Usage

## S3 method for class 'bcea'
multi.ce(he)

Arguments

he

A bcea object containing the results of the Bayesian modelling and the economic evaluation.

Value

Original bcea object (list) of class "pairwise" with additional:

p_best_interv

A matrix including the probability that each intervention is the most cost-effective for all values of the willingness to pay parameter

ceaf

A vector containing the cost-effectiveness acceptability frontier
