In hettreatreg: Heterogeneous Treatment Effects in Regression Analysis

#' National Supported Work -- Current Population Survey (NSW--CPS)
#'
#' The data set combines a subsample of the experimental treated units from NSW, constructed by Dehejia and Wahba (1999), with "CPS-1," a nonexperimental comparison group from CPS, constructed by LaLonde (1986).
#'
#' @return A data frame with 11 variables:
#' \item{\code{treated}}{1 if treated, 0 otherwise}
#' \item{\code{age}}{age}
#' \item{\code{age2}}{age squared}
#' \item{\code{educ}}{years of schooling}
#' \item{\code{black}}{1 if black, 0 otherwise}
#' \item{\code{hispanic}}{1 if Hispanic, 0 otherwise}
#' \item{\code{married}}{1 if married, 0 otherwise}
#' \item{\code{nodegree}}{1 if high school dropout, 0 otherwise}
#' \item{\code{re74}}{real earnings in 1974}
#' \item{\code{re75}}{real earnings in 1975}
#' \item{\code{re78}}{real earnings in 1978}
