#' @usage data("CMAPSS")
#' 
#' @format A list of the following 2 objects:
#' \itemize{
#' \item \code{train}{ a list of class "hhsmm.data" as the train dataset}
#' \item \code{test}{ a list of class "hhsmm.data" as the test dataset}
#' \item \code{subsets}{ a matrix containig the number of units in each subset of the CMAPSS data set (FD001-FD004) for the train and test datasets}
#' }
#' 
#' @details 
#' The turbofan engine data is from the Prognostic Center of Excellence
#' (PCoE) of NASA Ames Research Center, which is simulated by the Commercial Modular Aero-Propulsion
#' System Simulation (C-MAPSS). Only 14 out of 21 variables, by a method mentioned by Li, et al. (2019) 
#' are selected. The \code{train} and \code{test} lists are of class \code{"hhsmm.data"}, which is used 
#' in the \code{hhsmm} package.
