Interpretation of 'Dual response none'


How does the 'dual option none' contribute in the estimation of part worths? I'm using HB to analyze a CBC exercise. Also, how should the 'none' parameter be interpreted?

The help files address the first question: www.sawtoothsoftware.com/support/issues/ssiweb/online_help/hid_web_cbc_none.htm

For the second question, it depends.  If my none option was labeled "I would go without treatment to combat this disease" it's probably a lot easier to understand its meaning then if I say "I would not buy any of these 3 computers."  In the former, it has a specific meaning with a very real and tangible outcome (continued sickness, maybe risk of death, etc.).  The the latter, I probably don't know what it means (I would not buy a computer, I would go to a different store, I would delay my purchase for 6 months, etc.).
