#' Clinical Trial for Sepsis desease
#' 
#' Simulated clinical trial with two groups treatment about sepsis desease. See details.
#' 
#' This dataset is taken from 
#' \link[=http://biopharmnet.com/wiki/Software_for_subgroup_identification_and_analysis]{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())}
#' 
#' True subgroup is \emph{PRAPACHE <= 26 & AGE <= 49.80}
#' 
#' @format 470 patients and 13 variables.
