The problem of unstable coecients in the rank-ordered logit model has been traditionally interpreted as a sign that survey respondents fail to provide reliable ranking responses. This paper shows that the problem may embody the inherent sensitivity of the model to stochastic misspecification...

Several empirical studies conclude that a majority of economic agents ignore some of observed product attributes when choosing among discrete alternatives. Many of these ndings are based on latent class logit with partially constrained support points wherein the share of each point is...

This paper describes lclogit, a Stata module for estimating a discrete mixture or latent class logit model via the EM algorithm.
