I don't know about the recommending bit, but if you have the
(anonymous) ftp capability you can get /pc/ts/tslin29.arc from our
site.  This file contains a linear programming and a linear goal
programming program.

Sorry, but you have confused things in here.  Linear programming is
NOT a multivariate statistical technique (even if it can be applied
as a tool in least absolute deviations method in multiple regression
analysis.) Linear programming is a method for maximizing (or
minimizing) a linear function under linear constraints.  The
traditional LP task in vector notation is

   max z =     c'x
   subject to
               Ax < b
                  -
                x > 0
                  -
If you are looking for a newsgroup for LP questions, I think that
your best bet is sci.math.num-analysis.
