    Professor Baibing Li from Loughborough University of UK will visit the University of Washington and deliver a seminar talk on campus. You are cordially invited to join his seminar.

    Discrete choice modelling is a widely used econometric approach to analyse the behaviour of travellers. The multinomial logit model is one of the most commonly used models in discrete choice analysis. This research develops a new model, semi-parametric multinomial logit model. The developed model links travellers’ attributes and alternatives to the choice probabilities via a sensitivity function. This sensitivity function reflects the degree of travellers’ sensitivity to the changes in the travelling costs. A Bayesian approach is investigated to draw statistical inference for the semi-parametric logit model. An empirical study on travellers’ value of time that involves stated preferences about two train-related alternatives and two bus-related alternatives is conducted to illustrate the developed model.
