Learning Mixed Multinomial Logit Models
Multinomial logit (MNL) model is widely used to predict the probabilities of different outcomes. However, standard MNL model suffers from several issues, including but not limited to heterogeneous population, the restricted independence of irrelevant alternative (IIA) assumption, insufficient model …

Learning structure in nested logit models
… developing an estimation procedure for nested logit models that optimizes over the nesting structure in addition to the model parameters. Current estimation practices require an a priori specification of a nesting structure. We formulate the problem of learning an optimal nesting structure as a …

Stereotype Logit Models for High Dimensional Data
Gene expression studies are of growing importance in the field of medicine. In fact, subtypes within the same disease have been shown to have differing gene expression profiles (Golub et al., 1999). Often, researchers are interested in differentiating a disease by a categorical classification …

Estimating Desirable Cattle Traits Using Latent Class and Mixed Logit Models: A Choice Modeling Application to the U.S. Grass-Fed Beef Industry
… the preferences for cattle traits using mixed logit and latent class models. Choice experiment data from a 2013 mail survey of 1,052 U.S. grass-fed beef producers were used. The findings indicate that grass-fed beef producers generally preferred lower-priced, heavy animals that were …

Modeling preferences for innovative modes and services : a case study in Lisbon
… time, and occupancy is considered. Two types of models are used to investigate the preferences and acceptability of innovative modes and services -- nested logit models and mixed logit models. The main attributes in the systematic utilities include natural logarithm of travel time and cost, …

Endogeneity and Sampling of Alternatives in Spatial Choice Models
… two key requirements of practical spatial choice models. The omission of attributes causes endogeneity when the unobserved variables are correlated with the measured variables, precluding the consistent estimation of the model parameters. The consistent estimation while sampling alternatives in …

Modeling Intercity Mode Choice and Airport Choice in the United States
… in the United States. Nested and mixed logit models were developed to study national-level intercity transportation in the United States. A separate General Aviation airport choice model to estimates General Aviation person-trips and number of aircraft operations though more than 3000 …

A Bi-Level Programming Formulation and Heuristic Solution Approach for Traffic Control Optimization in Networks With Dynamic Demand and Stochastic Route Choice
… which can accommodate various route choice models to investigate how the extended logit models change the equilibrium flow by using various treatments on overlapping paths and how much system performance can be improved under various congestion levels. The implementation of five logit models …

Consumer Willingness-to-pay for Concord Grape Juice Treated by High-pressure Processing and Pulsed Electric Field
… a discrete choice model experiment. Mixed logit models and Latent-class logit models are used to estimate consumers’ willingness to pay toward different attributes including processing technology for the productions of Concord grape juice. We found that consumers tend to pay more for …

Modeling airline passenger choice : passenger preference for schedule in the passenger origin-destination simulator (PODS)
… in the airline industry. A review of the models used to represent that choice situation in the Passenger Origin-Destination Simulator (PODS) was undertaken for two reasons. First, the development of computational capabilities has lead to advancements in consumer choice theory that enabled …

Three Essays on: Hedging in China's Oil futures market; Gold, Oil and Stock Market Price Volatility links in the USA; and, Currency Fluctuations in S.E. and Pacific Asia
… Dynamic Bi-variate GARCH and constant volatility models are estimated to derive the optimal hedging ratios and hedging effectiveness of China fuel oil futures. That effectiveness is assessed by several criteria, for both in- and out-of-sample periods. Essay 2 aims to investigate the relationship …

Evaluation of benefits and effectiveness of smart cards for public transport
… implemented. In the data analysis, two different models are discussed: firstly standard logit models are used to analyse the joint RP and SP data. Secondly, two kinds of new techniques: fuzzy logic (FL) and artificial neural network (ANN) methods are introduced as an alternative to model discrete …

Modelling freeway pedestrian crossing behaviour in Cape Town
… risk assessment to estimate a series of choice models and based on a 300 participants survey, intercepted along three Cape Town freeways, ordered-responses logit models were developed to estimate risk perception thresholds for both general risk perception (prior to the choice experiment) as well …
