Abstract:

In the current paper, the authors propose a new multinomial probit-based model formulation for integrated choice and latent variable (ICLV) models, which, as the authors show in the paper, has several important advantages relative to the traditional logit kernel-based ICLV formulation. The time for convergence in the new ICLV formulation and estimation procedure is of the order of 30 minutes to 80 minutes for sample sizes ranging from 500 observations to 2000 observations, in contrast to much longer times for convergence experienced in traditional ICLV model estimations (that is, if convergence is achieved at all in these estimations).
