#' Clinical Trial for Sepsis desease
#' 
#' Simulated clinical trial with two groups treatment about sepsis desease. See 
#' details.
#' 
#' This dataset is taken from 
#' \href{http://biopharmnet.com/subgroup-analysis-software/}{SIDES
#' method}.
#' 
#' \code{Sepsis} contains simulated data on 470 subjects with a binary outcome 
#' survival, that stores survival status for patient after 28 days of treatment,
#' value of 1 for subjects who died after 28 days and 0 otherwise. There are 11 
#' covariates, listed below, all of which are numerical variables.
#' 
#' Note that contrary to the original dataset used in SIDES, missing values have
#' been imputed by random forest \code{(randomForest::rfImpute())}. See file 
#' data-raw/sepsis.R for more details.
#' 
#' True subgroup is \emph{PRAPACHE <= 26 & AGE <= 49.80}. \emph{NOTE:} This 
#' subgroup is defined with the \emph{lower} event rate (survival = 1) in
#' treatement arm.
