#' @details
#' A subset of data from the University of Massachusets Aids
#' Research Unit (UMARU) IMPACT study.
#' \cr
#' This came from two concurrent randomized trials of residential
#' treatement for durg abuse, in order to compare planned
#' durations of admission.
#' \cr
#' Site A randomized 444 participants to compare 3 and 6 month
#' stays in a therapeutic community. They were
#' trained to recognize triggers for relapse and taught skills to
#' cope without using drugs.
#' \cr
#' Site B randomized 184 participants to receive either a 6 or 12
#' month stay in a highly structured communal therapeutic
#' community.
#' \cr \cr
#' This is a subset of the original dataset.
#' \cr \cr
#' Columns are:
#' \describe{
#'  \item{ID}{Identification code.}
#'  \item{AGE}{Age (years).}
#'  \item{BECK}{Beck Depression score on admission.}
#'  \item{IVHX}{IV drug use history (a \code{factor}):

#'  \item{TREAT}{Treatment randomization.
#'               'Short' is 3 months in site A, 6 months in site B.
