% February 23, 1982
% 
% The 1982 annual meetings of the American Statistical Association (ASA)
% will be held August 16-19, 1982 in Cincinnati.  At that meeting, the ASA
% Committee on Statistical Graphics plans to sponsor an "Exposition of 
% Statistical Graphics Technology."  The purpose of this activity is to
% more fully inform the ASA membership about the capabilities and uses of
% computer graphcis in statistical work.   This letter is to invite you to 
% participate in the Exposition.
% 
% Attached is a set of biomedical data containing 209 observations (134
% for "normals" and 75 for "carriers").  Each vendor of provider of
% statistical graphics software participating in the Exposition is to
% analyze these data using their software and to prepare tabular, graphical
% and text output illustrating the use of graphics in these analyses and
% summarizing their conclusions.  The tabular and graphical materials must be
% direct computer output from the statistical graphics software; the
% textual descriptions and summaries need not be.  The total display space
% available to each participant at the meeting will be a standard poster-
% board (approximately 4' x 2 1/2').  All entries will be displayed in one
% location at the meetings, together with brief written commentary by
% the committee summarizing the results of this activity.

% THE DATA
% 
%    The following data arose in a study to develop screening methods to
% identify carriers of a rare genetic disorder. Four measurements m1,
% m2, m3, m4 were made on blood samples. One of these, m1, has been used
% before.
%    Because the disease is rare, there are only a few carriers of
% the disease from whom data are available. The data come in two files,
% one for normals and one for carriers of the disease. A description of
% the files is provided. The data have been stripped of the names and
% other identifiers. Otherwise the data are as received by the analyst.
% 
% 
% PURPOSE OF THE ANALYSIS
% 
%    The purpose of the analysis is to develop a screening procedure to
% detect carriers and to describe its effectiveness.  Experts in the
% field have noted that young people tend to have higher measurements.
% The laboratory which prepared the measurements is worried that there
% may be a systematic drift over time in their measurement process.
% These effects should be considered in the analysis.  Can graphical
% displays show the differences between the distributions of carriers
% and normals?
