In MRMCaov: Multi-Reader Multi-Case Analysis of Variance

#' Multi-reader multi-case dataset
#'
#' Data from a multi-reader multi-case study conducted by Kundel et al. (1997)
#' to compare the clinical diagnostic accuracy of hard-copy readings of
#' screen-film bedside chest radiographs and both hard- and soft-copy readings
#' of computed radiographs from separate groups of patients in a medical
#' intensive care unit.
#'
#' @format A data frame with 760 rows and 5 variables:
#' \describe{
#'   \item{reader}{reader identifier}
#'   \item{treatment}{numeric identifier for treatment modality}
#'   \item{treatment_name}{name of treatment modality}
#'   \item{case}{patient identifier}
#'   \item{truth}{true case status (1 = diseased, 0 = non-diseased)}
#'   \item{rating}{ordinal reader ratings of case status}
