\title{Left Ventricular Ejection Fraction}
\description{
  Left ventricular ejection fraction in patients with malignant ventricular
  tachyarrhythmias including recurrence-free month and censoring.
}
\usage{hohnloser}
\format{
  A data frame with 94 observations on 3 variables.
  \describe{
    \item{\code{EF}}{
      ejection fraction (\%).
    }
    \item{\code{time}}{
      recurrence-free month.
    }
    \item{\code{event}}{
      status indicator for \code{time}: \code{0} for censored observations and
      \code{1} otherwise.
    }
  }
}
\details{
  The data was used by Lausen and Schumacher (1992) to illustrate the use of
  maximally selected statistics.
