Prostate cancer dataset
}
\description{
The \code{prostate} dataset was obtained from a study carried in Le (2006). This study was conducted to evaluate the clinical usefulness of the level of acid phosphatase in blood serum (APBS) x 100 to predict whether
nodal involvement is present.

\usage{data(prostate)}

  \describe{
    \item{\code{marker}}{level of acid phosphatase in blood serum. Numeric vector}
    \item{\code{status}}{true disease status (absence/presence of nodal involvement). Numerical vector (0=absence, 1=presence)}
