     `Titanic', summarized according to economic status
     (class), sex, age and survival.

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

     No     Name         Levels
      1     Class        1st, 2nd, 3rd, Crew
      2     Sex          Male, Female
      3     Age          Child, Adult
      4     Survived     No, Yes

     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 passen-
     gers to the ``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
     `Titanic', the last years saw a rise in public interest
     in the Titanic.  Very detailed data about the passen-
     gers is now available on the Internet, at sites such as
     Encyclopedia Titanica (<URL:
     http://www.rmplc.co.uk/eduweb/sites/phind>).

     The source provides a data set recording class, sex,
     age, and survival status for each person on board of
     the Titanic, and is based on data originally collected
     by the British Board of Trade and reprinted in:
