Random Covariance Heterogeneity in Discrete Choice Models
In this paper, we extend the standard discrete choice modelling framework by allowing for random variation in the substitution patterns between alternatives across respondents, leading to increased model flexibility. The paper shows how such a Mixed Covariance model can be specified either with purely random variation or with a mixture between random and deterministic variation. Additionally, t...
متن کاملHeterogeneity in dynamic discrete choice models
We consider dynamic discrete choice models with heterogeneity in both the levels parameter and the state dependence parameter. We rst analyse the purchase of full fat milk using a long consumer panel (T > 100) on many households. The large T nature of the panel allows us to consistently estimate the parameters of each household separately. This analysis indicates strongly that the levels and T...
متن کاملNonparametric Discrete Choice Models with Unobserved Heterogeneity
In this research, we provide a new method to estimate discrete choice models with unobserved heterogeneity that can be used with either cross-sectional or panel data. The method imposes nonparametric assumptions on the systematic subutility functions and on the distributions of the unobservable random vectors and the heterogeneity parameter. The estimators are computationally feasible and stron...
متن کاملQuasi-Random Simulation of Discrete Choice Models
We describe the properties of (t,m, s)-nets and Halton draws. Four types of (t,m, s)-nets, two types of Halton draws, and independent draws are compared in an application of maximum simulated likelihood estimation of a mixed logit model. All of the quasi-random procedures are found to perform far better than independent draws. The best performance is attained by one of the (t,m, s)-nets. The pr...
متن کاملDiscrete choice models based on random walks
We show that a large class of discrete choice models which contain the Markov chain model introduced by Blanchet, Gallego, and Goyal (2013) belong to the class of discrete choice models based on random utility. © 2016 Elsevier B.V. All rights reserved.
