I have run several HB models on my MaxDiff data, but Now I am not sure how to report the results and which model should I choose as the best fit?
I have followed the recommendations in chapter 12 of your advanced CBC book and generated the 95% CI & the % confidence of each level I am valuing. Still, I found that in the articles they report Standard errors, how can these two be correlated?
Furthermore, how can I discover the heterogeneity between respondents regarding each level/item and how to check if they are significant?
Finally, if I have only one hold-out, how can I check the hit rate of my model regarding this hold-out task or test the model predictability?
One last point, how can I calculate the degrees of freedom for the Logit in maxdiff case 2 if I have 31 total levels & presenting 6 of them (each time) and each respondent evaluated 10 different scenarios ?
Thank you very much
