I am currently using Splus 2000 (Windows) as part of
my Honours project in Statistics at the University of
Natal, Pietermaritzburg. Part of my project is
multiple regression based. I am trying to get the
PRESS statistic for each model given by all subsets
(procedure leaps). I was wondering whether there was a
direct way of doing this, or whether the jackknife
procedure needs to be used, if so any advice on how
this might be used would be appreciated.
With thanks
Fay Hughes (Miss)
