In giabaio/BCEs0: Bayesian models for cost-effectiveness analysis in the presence of structural zero costs

#' BCEs0. A R package to implement Bayesian models for cost-effectiveness
#' analysis in the presence of structural zero costs
#' 
#' Implements a full Bayesian cost-effectiveness analysis in the case where the
#' cost variable is characterised by structural zeros. The package implements
#' the Gamma, log-Normal and Normal models for the cost variable and the Gamma,
#' Beta, Bernoulli and Normal models for the measure of clinical effectiveness.

#' Bayesian model for the cost-effectiveness of acupuncture
#' 
#' This data set contains a sample of the data used in the Bayesian analysis
#' used to model the cost-effectiveness of acupuncture in the management of
#' chronic headache. Data consists in the measure of effectiveness (in terms of
#' annual QALYs) for the two arms of the trial ($t=0$ indicates usual care,
#' while $t=1$ indicates usual care and in addition up to 12 acupuncture
#' treatments over three months from appropriately trained physiotherapists).
#' Also, the dataset contains the values of the upper bounds for the average
#' and standard deviation of the cost distribution.
