I would like to set up a choice experiment consisting of two alternatives and one status quo. The alternatives and the status quo are defined by 5 attributes, which have between two and four levels. The levels in the status quo, however, should be fixed and two of the attribute levels should only appear in the status quo and not in the two alternatives. Is it possible to define the status quo in a way that afterwards allows analyzing the switch from status quo to the alternatives based on the fixed attribute levels?
Thank you very much for your help!
