Essays on choice modeling
The increased interest in modeling preference heterogeneity in Choice Experiments (CE) data has promoted the use of choice models within the family of Logit Mixture models. However, researchers have scarce guidance on how to select the appropriate model. A Monte Carlo study is set up to analyze the …

Nonparametric choice modeling : applications to operations management
With the recent explosion of choices available to us in every walk of our life, capturing the choice behavior exhibited by individuals has become increasingly important to many businesses. At the core, capturing choice behavior boils down to being able to predict the probability of choosing a …

Mode Choice Modeling Using Artificial Neural Networks
… primary goal of this thesis is to develop mode choice models using artificial neural networks and compare the results with traditional mode choice models like the multinomial logit model and linear regression method. The data used for this modeling is extracted from the American Travel Survey …

Choice modeling with observed and unobserved information search
… to the continuous effort of enhancing discrete choice models with richer behavior representations by explicitly modeling the information search process leading up to a choice. Information search includes information acquisition as well as information processing, the respective observability of …

Choice Modeling and Assortment Optimization on the Transformer Model
The problem of modeling customer choices and finding assortments with maximal revenue has been widely studied in revenue management. Random utility models (RUMs) are typically used to model choice. These models implicitly enforce a rational decision making process whereby a customer is endowed with …

Choice modeling and recommendation optimization in presence of context effects
Random Utility choice models are supervised learning tools that can be used to estimate the choice behavior of customers facing multiple options. This is accomplished through assigning a utility value to each option and deriving a choice probability for each option. In the presence of context …

Incorporating attitudes in airline itinerary choice : modeling the impact of elapsed time
… experiment is designed and conducted to collect choice data. Psychometric indicators are used to capture attitudes that are explained with socio-demographics and trip characteristics in a multiple indicator-multiple causes (MIMC) model. The MIMC model is then combined with the choice model to …

Factors affecting public support of transportation policies : using an international survey and hybrid discrete choice modeling
What transportation policies do people support? What factors affect people's policy support? Detangling people's support of transportation policies is a way to understand public needs, to understand how the public evaluates and envisions the role of government in shaping the current as well as …

The planning and analysis implications of automated data collection systems : rail transit OD matrix inference and path choice modeling examples
… the algorithm. The other study is of rail path choice, which employs the Logit and Mixed Logit models to examine revealed public transit riders' travel behavior based on the inferred OD matrix and the transit network attributes. This study is based on two data sources: the rail trip OD matrix …

Estimating Desirable Cattle Traits Using Latent Class and Mixed Logit Models: A Choice Modeling Application to the U.S. Grass-Fed Beef Industry
… 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 small-to-medium framed and easy to handle …

ANALYSIS OF ACTIVITY CHOICE: THE ROLE OF ACTIVITY ATTRIBUTES AND INDIVIDUAL SCHEDULES
… is to view travel as a result of our activity choices and scheduling decisions. Therefore, better understanding of activity choice, planning time horizons, and activity attributes will lead to more accurate demand forecasts. This dissertation extends the current activity choice modeling …

Empirical Studies of Discrete Choice Models in Health, Fertility, and Voting
Almost everything that we do involves a choice. In recent years there has been a growing interest in the development and application of quantitative statistical methods to study choices made by individuals with the purpose of gaining a better understanding of how choices are made and also to …

Inventory positioning in modern retail
… and algorithms. First, we study the problem of choice modeling and assortment optimization. Choice models aim to capture customer preferences across products and have been extensively studied.

Segmentation of the market for labeled ornamental plants by environmental preferences: A latent class analysis
… Latent class analysis was conducted using choice modeling survey results and respondent scores on the New Environmental Paradigm scale. The results show that when accounting for environmental preferences, consumers can be grouped into two market segments. Relative to each other, these …

Understanding consumers' ornamental plant preferences for disease-free and water conservation labels
… plant disease and irrigation water use. A choice modeling survey was utilized to estimate consumers' willingness to pay a premium for six ornamental plants with disease-free and/or water conservation certification labels. The results of the mixed logit models show consumers are willing to …

Stated and Revealed Preference Valuation of Forest Ecosystems
… programs. In these first two chapters, choice modeling method is employed to elicit the respondents' preferences, and I also use bootstrap method to get robust estimation results for small sample size data. The last chapter employed revealed preference method to evaluate the economic …
-
Endogeneity and Sampling of Alternatives in Spatial Choice Models
… are 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 …

Use of discrete choice models with recommender systems
… dissertation, we investigate the use of discrete choice models as a radically new technique for giving personalized recommendations. Discrete choice modeling allows the integration of item and user specific data as well as contextual information that may be crucial in some applications. By giving …
