\format{
  A 4-dimensional array resulting from cross-tabulating 2201
  observations on 4 variables.  The variables and their levels are as
  follows:

  \tabular{rll}{
    No \tab Name \tab Levels\cr
    1 \tab \code{Class} \tab 1st, 2nd, 3rd, Crew\cr
    2 \tab \code{Sex} \tab Male, Female\cr

\details{
  The sinking of the Titanic is a famous event, and new books are still
  being published about it.  Many well-known facts---from the
  proportions of first-class passengers to the \sQuote{women and
    children first} policy, and the fact that that policy was not
  entirely successful in saving the women and children in the third
  class---are reflected in the survival rates for various classes of
  passenger.

  These data were originally collected by the British Board of Trade in
  their investigation of the sinking.  Note that there is not complete
  agreement among primary sources as to the exact numbers on board,
  rescued, or lost.

  Due in particular to the very successful film \sQuote{Titanic}, the last
  years saw a rise in public interest in the Titanic.  Very detailed
  data about the passengers is now available on the Internet, at sites
  such as \emph{\I{Encyclopedia Titanica}}
  (\url{https://www.encyclopedia-titanica.org/}).
