In BRBVS: Variable Selection and Ranking in Copula Survival Models Affected by General Censoring Scheme

#' Age-Related Eye Disease Study (AREDS)
#'
#' A real dataset of bivariate interval-censored data with 629 subjects and 4 non-genetic covariates
#' and 1 genetic covariate. The dataset is selected from the Age-related Eye Disease Study (AREDS)
#' (AREDS Group, 1999). Two events are the progression times (in years) to late-AMD in the left and
#' right eyes.

#' @format ## `AREDS`
#' A data frame with 628 patients (rows) and 11 columns:
#' \describe{
#'   \item{SevScale1E}{Severity scale associated with the right eye}
#'   \item{SevScale2E}{Severity scale associated with the left eye}
#'   \item{ENROLLAGE}{Age at baseline}
#'   \item{rs2284665}{SNP covariate highly associated with late-AMD progression (GG, GT, TT)}
#'   \item{cens1}{Recurrence censoring variable in the right eye}
#'   \item{cens2}{Recurrence censoring variable in the left eye}
#'   \item{cens}{Overall survival censoring variable}
#'   \item{t11}{Start of follow-up in days right eye}
#'   \item{t12}{Time to recurrence or last follow-up in days right eye}
#'   \item{t21}{Start of follow-up in days left eye}
#'   \item{t22}{Time to recurrence or last follow-up in days left eye}
