Dear S-plus Specialists,
We have carried out discriminant analysis using SPLUS-4 (Windows95), release
3, with the lda function (Ripley library) for predicting group membership
from 32 explanatory variables. We wish to assess which of this variables
contributed most strongly to discrimination and to optimise variables
selection.
Other packages such as SPSS allow this assessment by judging standardised
discriminant function coefficients and correlation between function scores
and explanatory variables. SPSS also allows the statistical significant of
each discriminant functions to be judged from wilk's lambda tranformed to
chi square.
Are these procedures possible with S-PLUS?
Thanks
Stephanie
