data describing
+the association between an outcome and several explanatory variables.  In a
+typical modeling situation statistical analysis often involves a large number 
+potential explanatory variables and frequently only partial subject-matter
+knowledge is available.  Therefore, selecting the most suitable variables for a
+model in an objective and practical manner is usually a non-trivial task.  This
+package performs augmented backward elimination and checks the stability of the
+obtained model.  Augmented backward elimination combines significance or
+information based criteria with the change in estimate to either select the
+optimal model for prediction purposes or to serve as a tool to obtain a
+practically sound, highly interpretable model.")
