  ===== DA-DA-DA DAAAAA =================================

  Since many people asked me to port some of my statistics
  stuff to octave I did so. A contents-file is attached
  to this mail. The files are tar-ed and can be feched
  in two ways and four formats.

http://www.maths.lth.se/matstat/andersh/stixoct.tar
                                       /stixoct.tar.Z
                                       /stixoct.tar.Z.uu
                                       /stixoct.tar.uu
ftp://ftp.maths.lth.se/pub/transfer/andersh/stixoct.tar  et.c.

  Note that it is a quick hack and that spurious warning
  messages and matlab non-octave portable code are still
  there. I have however removed all routines that do not
  work at all with octave.

  Best wishes,

  Andy
