Scalable likelihood-based inference for limited dependent variable models

David T. Frazier, Ruben Loaiza-Maya, Didier Nibbering

Limited dependent variable models are central to empirical economics, but likelihood-based inference is infeasible when likelihoods involve high-dimensional integration over latent…

A Multinomial Probit Model for Asymmetric Choice Responses

Cash Looi, Ruben Loaiza-Maya, Didier Nibbering

Standard multinomial probit (MNP) models specify symmetric latent utility distributions, implying that choice probabilities respond symmetrically to positive and negative covariate…

Conjugating Variational Inference for Large Mixed Multinomial Logit Models and Consumer Choice

Weiben Zhang, Ruben Loaiza-Maya, Michael Stanley Smith +1

Heterogeneity in multinomial choice data is often accounted for using logit models with random coefficients. Such models are called "mixed", but they can be difficult to estimate f…

Robustifying Approximate Bayesian Computation

Chaya Weerasinghe, David T. Frazier, Ruben Loaiza-Maya +1

Approximate Bayesian computation (ABC) is one of the most popular "likelihood-free" methods. These methods have been applied in a wide range of fields by providing solutions to int…

Natural Gradient Hybrid Variational Inference with Application to Deep Mixed Models

Weiben Zhang, Michael Stanley Smith, Worapree Maneesoonthorn +1

Stochastic models with global parameters and latent variables are common, and for which variational inference (VI) is popular. However, existing methods are often either slow or in…
