From the user: See examples from Sawtooth ([https://sawtoothsoftware.com/conjoint-analysis/acbc|https://sawtoothsoftware.com/conjoint-analysis/acbc|smart-link] ) and Qualtrics ([https://www.qualtrics.com/fr/gestion-de-l-experience/etude-marche/analyse-conjointe/?rid=langMatch&prevsite=en&newsite=fr&geo=&geomatch=|https://www.qualtrics.com/fr/gestion-de-l-experience/etude-marche/analyse-conjointe/?rid=langMatch&prevsite=en&newsite=fr&geo=&geomatch=|smart-link] ) .

We are using the CBC module in Displayr quite a bit and I wonder if there is one coming for adaptative choice-based conjoint (ACBC)?

In the meantime, I wonder if you have recommendations on building the designs and analysing ACBC. From relevant literature (see for example, excerpts from Cunningham, Deal & Chen, 2010 ([https://rdcu.be/deIj6|https://rdcu.be/deIj6|smart-link] ) ), it looks like the BYO, screeners, and choice tournament sections can be analyzed together. However, they wouldn’t have the same basis (some options won’t be seen at all by participants, probability 0), it’s unclear to me how they can be combined to run a multinomial logit model.
