Thank you, Michiel, for the information regarding the MNL properties and probabilities.
I assume these probabilities (the first 10 of the 72 below) are the chance of respondents choosing drug or no drug for each choice set?

Dear, Michiel,

I hope you're staying safe, sane and healthy. Thank you so much for your input and extensive response very late on Friday night :)

As age is an attribute with levels, I assume there's no way to have a continuous level?
Therefore as you stated are my options either more levels [25, 35, 45, 55, 65, 75], or categories i.e. 18-39 years = 0, 40-59 years = 1, 60+ years = 2 [0,1,2 ...

I want to set 2 of the attributes (patient age and presence of comorbidities) as part of a patient profile so they need to be the same across ...

Hi Michiel
