Heterogeneity in mode choice behavior: A spatial latent class approach based on accessibility measures

open access: yesJournal of Transport and Land Use, 2023
We propose a method to estimate mode choice models, where preference parameters are sensitive to the spatial context of the trip origin, challenging traditional assumptions of spatial homogeneity in the relationship between travel modes and the built ...

Comparison of Criteria for Choosing the Number of Classes in Bayesian Finite Mixture Models. [PDF]

open access: yesPLoS ONE, 2017
Identifying the number of classes in Bayesian finite mixture models is a challenging problem. Several criteria have been proposed, such as adaptations of the deviance information criterion, marginal likelihoods, Bayes factors, and reversible jump MCMC ...
