Hello,

I am attempting to reproduce results in SAS that Huberty & Olejnik (2006)
discuss in section 8.5 (p. 143, for example) where these authors perform a
descriptive discriminant analysis (what SAS calls a canonical discriminant
analysis) in SPSS. I am using PROC DISCRIM with the CANONICAL option,
however:

This situation is a 2 factor MANOVA situation. Apparently SPSS performs the
MANOVA and DDA all part of the same MANOVA program. In SAS, I am using
separate calls to GLM and DISCRIM and am unable to reproduce the DDA results
in DISCRIM for each of the main effects (the GLM results match the SPSS
output, but not the DDA results). I assume this is b/c I am not able to
specify the correct Error SSCP matrix in DISCRIM (but I'm not 100% sure
about that...).

Does anyone have any suggestions or expertise in this area?

Thank you,

Dan
