I am using the DOE Choice Design function to create a design for a discrete choice experiment. I would like to disallow some combinations of attribute levels due to the fact that they don't make logical sense together, and I would like to decrease the cognitive burden on the respondents. (Ex- disallowing the combination of "no jobs lost" and "8 in 10 households struggle financially")
I am aware the custom DOE option allows for disallowed combinations, but I still want to be able to implement the prior means/variance matrix as permitted in the "choice design" option. As far as I can tell, using these priors isn't possible in the custom DOE and disallowed combinations isn't possible in the choice design tab. Is there a way I can disallow combinations while still being able to implement my prior means/variance matrix?
