Fit mult-option data with Multinomial distributuion or normal distribution?

Dear Bayesian model experts,

Assuming one has data with 20 categories, multinomial distribution or normal distribution, which one is more suitable to this dataset?Thank you very much.


If the categories have no natural ordering, multinomial. If the categories have an ordering, you’ll want to use an ordinal model. A normal model would certainly be inappropriate in any case I can imagine given your description.
