Is there anyway to incorporate the dual-response none in the hit-rate estimation?


I wonder whether I should count the prediction as a "miss" for hit-rate estimation or not if the respondents choose the dual-response as "none". Is there anyway I can use this information to improve my prediction?

Thank you very much

I don't know how computing the hit-rate including the dual-response none questions will "improve your prediction."  But, the way to do it is to treat the dual-response none tasks as a separate task to be predicted.  You compare the None utility for each respondent to the utility of the concept chosen by the respondent in that task.  If the respondent answered "None" and the None utility exceeds the utility of the concept that respondent picked in the task, then it is a "hit"; otherwise a miss.
