Thank you so much Kenneth for your help on HPD... That's really helpful!!
I just want to be sure on "Draws for the part-worth you want to compute the HPD". Here, I am working on CBC design & could see 3 measures (Individual Utilities (ZC Diffs), Individual Utilities (Raw), alpha draws). Which one do I need to consider for my HPD calculation?? From Sawtooth, I could see one summary sheet with Average Utility score along with Standard Deviation and these are based on "Individual Utilities (ZC Diffs)". So I was assuming to use "Individual Utilities (ZC Diffs)" for my HPD calculation. Kindly suggest.
(From Sawtooth support, I got a suggestion to use "alpha draws", but this is available for each of the iteration (instead of Respondent/record)... So I am confused)
