The nested logit model
WebNested Logit Model • First estimate an MNL for the AI(q) alternatives of the lower nest, taking care of omitting all those variables (z) which take the same value for this subset of options. • The utility of the composite alternative has two components: – One that consists of the expected maximum utility (EMU) of the lower nest options, and Weband multinomial logit models by clustering similar alternatives into nests. Because the nested logit model is a direct generalization of the alternative-specific conditional logit model (also known as McFadden’s choice model), you may want to read[R] asclogit before continuing. By default, nlogit uses a parameterization that is consistent ...
