#' Two marker values with event time and censoring status for the subjects in Mayo PBC data.
#' @docType data
#' @usage data(mayo)
#' @keywords datasets
#' @format A data frame with 312 observations and 4 variables: time (event time/censoring time), censor (censoring
#'        indicator), mayoscore4, mayoscore5. The two scores are derived from 4 and 5 covariates
#'        respectively.
