MNL is an aggregate logit model assuming that consumer preference is homogeneous so that the part-worth coefficients in Eq. (2.3) are deterministic and the same across individuals. Mixed logit accounts for heterogeneity of consumer preferences 7Pr[ε < x] = exp[− exp(−x)] 21 treating part-worth coefficients as a distribution across individuals.
