Conjoint question: parameter estimates all levels

[Rene]

Dear users,

I set up a conjoint design with 4 attributes, each with 3 levels. Now I gathered my data I want the part-worths of the 4 attributes AND of all levels individually. My problem is that i don't know how i can generate the part-worths of all levels individually (12 in total). I managed to generate the part-worths of the attributes (price, service, assortment and quality) with the code underneath. What code is needed to generate the part-woths of the individual levels?

Thanks in advance!

Although I have no experience in this topic-area, I did find three hits on the SAS support website http://support.sas.com/ when using the following Google advanced search:

Hopefully one of these resources will be useful to your interest.
