Subject:      [Q] using CANDISC and STEPDISC with nonparametric data

Hi,
 
I am using the discrimination procedures to try and find out about my
sonar data. It is definitely nonparametric data as the distributions are
not normal.
 
The "Introduction to Discrimination" chapter in the SAS/STAT manual says
that "CANDISC and STEPDISC perform.......that require the within-class
distributions to be approximately normal, but these procedures can be
used descriptively with non-normal data". (This is in the manual for
version 6.03 - I am using 6.10 on the mac but dont have access to any
recent manuals)
 
I was wondering what they mean by use them descriptively ? Has anyone
else used them descriptively ? Any help would be appreciated
 
thanks in advance
neil
