% Set left margin - The default is 1 inch, so the following

\setlength{\oddsidemargin}{0.25in}

% Set width of the text - What is left will be the right margin.
% In this case, right margin is 8.5in - 1.25in - 6in = 1.25in.

In the discriminant module in SYSTAT and using \verb+iris.syz+, do five analyses: one with all four variables included, and four with one of the variables removed.  Present the number of cross-validated errors (jacknifed) for each of the five analyses.

\bigskip

Using \verb+fisheriris+ in MATLAB and the 

\verb+ClassificationDiscriminiant.fit+ 

\noindent routine, carry out the same five analyses as you did in SYSTAT, but do  5-fold cross-validations.  What are the number of errors (cross-validated) for each of the five analyses and how do they compare with the jacknifed errors found in SYSTAT.
