Source

This dataset is included in the earth package because it is a convenient vehicle for illustrating earth's GLM and factor handling.

The dataset was compiled by Frank Harrell and Robert Dawson: http://biostat.mc.vanderbilt.edu/twiki/pub/Main/DataSets/titanic.html

For this version of the Titanic data, passenger details and incomplete cases were deleted and the name changed to etitanic to minimise confusion with other versions ("e" because it is part of the earth package).
