% The biomed dataset to develop screening methods to identify carriers
% of a rare genetic disorder.  Because the disease is rare, there are
% only a few carriers of the disease from whom data are available.

%       X = BIOMED(VAL)
%
% By default objects with missing values are removed. When something else
% is desired, use one of the options in MISVAL for VAL.
%
% This is the ''biomed' dataset of the <a href="http://lib.stat.cmu.edu/datasets/">StatLib Datasets Archive</a>.
% Just the original features 3, 5, 6, 7 and 8 are used.
