#' Simulated data to use with the \code{\link{rpsftm}} function.
#'
#' @format A simulated data frame with 9 variables and 1000 observations representing a study where participants 
#' were randomly assigned to receive treatment immediately or deferred. Participants in the deferred 
#' arm could crossover and receive treatment. The primary endpoint was time to disease progression.
#' 
#' The data are based on a randomized controlled trial Concorde \doi{10.1016/S0140-6736(94)90006-X}
