Glerum_WDCA_13 TRANSP-OR TALK Glerum, Aurélie Hurtubia, Ricardo Nguyen, My Hang Bierlaire, Michel Enhanced measurement equations for latent class choice models 2013 Eighth workshop on discrete choice models EPFL, Lausanne, Switzerland May 31, 2013 Integrating psychometric indicators in latent class choice models allows to enhance the characterization of the latent classes. In this research, we consider measurement equations that include socio-economic indicators of the decision-makers. We show that such a specification increases the significance of the parameters relative to the class-membership relation and leads to a better interpretability of the behavior of individuals in the latent classes. The method is applied to a transportation mode choice case study in Switzerland.
