in my recent study the price attribute has four levels (0%; 5%; 10%; 15%).
Based on the real price input by the respondent, the system then calculates his four price values shown in the CBC.
Now my question refers to the linear coding of the price attribute in CBC-HB. I know that single-digit values should be used but struggle with defining those in my scenario.
Can someone please point me in the right direction and maybe give a hint regarding the interpretation of the results?
Thank you very much in advance!
