First of all I sincerely would like to thank you for your help and also for your patience for my repetitive question and for "my covariates". I really am trying to understand these processes that you have described. But I am still not able to completely grasp it.
When I apply the Bayesian approach, I should be examining the alpha file, however how should I make the comparison between groups, as I need to document the interpretation of these. Should I just look through the output after convergence point, as you have described before, as <0 or >0 a and come up with the confidence levels?
And for the frequentist approach, do i need to take the range between attribute levels on zero-centered part-worth utilities ? to be able to test attribute importances? also by part-worth parameters do you mean the average utilities on summary table?
My apologies again for this repetitive and very simple questions but I am just having difficulties to get this.
