I am currently analyzing a conjoint , I have 5 attributes, one of which is a fare class (First, business, premium, economy) and another is price.
My simulation is looking for optimizing share of preference across the three fare class. So in my scenario, you have 4 products, differing from one another to the extent that one is for each fare class (so 4 products), and price as a variable. All other attributes are the same.
In my simulation, i would like to set a condition, that prices have to be the same across fare classes. So, scenario 1 could be all prices would be worth 200, scenario 2 with 250, etc.
How can I set this constrain? Otherwise I have scenarios with price differing across fare classes, which does not match my requirements. I hope I have been clear enough
