Re: Status quo levels in discrete choice experiment

Dear Michiel,
so far I´ve used dummy coding for my estimations of the above mentioned model.
Is there any indication to use effects coding instead of dummy coding?
I´ve seen that some papers are using effects coding for categorical variables but am not sure if that might also make sense for my model.
I suppose no, because effects coding prevents from choosing the reference level arbitrarily, but as I have a fixed status quo dummy coding with SQ levels as reference levels seems to make most sense?!
Thankful for any information from your point of view!
Thanks and best,
J.
