Inclusion of latent variables in Mixed Logit models: Modelling and forecasting
(2010)
Travel demand models typically use mainly objective modal attributes as explanatory variables. Nevertheless, it has been well known for many years that attitudes and perceptions also influence users' behaviour. The use of ...
Forecasting vs. observed outturn: Studying choice in faster inter-island connections
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Passenger demand and, in particular, mode choice between the islands of Gran Canaria and Tenerife has experienced important changes in the last decade. In 2005 the jetfoil, which had been the dominant mode for many years, ...
Modeling safety as a perceptual latent variable to assess cycling infrastructure
(Elsevier, 2018-05)
Perceived safety is a relevant construct that affects cyclists’ behavior. Nevertheless, this qualitative
attribute has not been adequately considered in infrastructure design preference models.
Even though the use of ...
Combining multiple imputation and control function methods to deal with missing data and endogeneity in discrete-choice models
(Elsevier, 2020)
While collecting data for estimating discrete-choice models, researchers often encounter missing information in observations. In addition, endogeneity can occur whenever the error term is not independent of the observed ...
A multiple indicator solution approach to endogeneity in discrete-choice models for environmental valuation
(2018)
Endogeneity is an often neglected issue in empirical applications of discrete choice modelling despite its severe consequences in terms of inconsistent parameter estimation and biased welfare measures. This article analyses ...
Unveiling physicians’ choice of practice location: evidence from observed migration
(2019-03-22)
This paper exploits the revealed preferences of all generalist physicians graduated in Brazil between 2001 and 2013 to examine the factors influencing their decision of practice location after graduation. We estimate ...
CHAIRS: A choice-based air transport simulator applied to airline competition and revenue management
(2022)
In Revenue Management (RM) systems, information censoring and the interaction between the forecasting and optimization stages, increases the costs and complexity of performance analysis using historical data. An affordable ...
Confidence intervals to bound the value of time
(PERGAMON-ELSEVIER SCIENCE LTD, 2001)
The derivation of a subjective value of time (SVT) requires finding the marginal rate of substitution between travel time and cost in a travel choice model. In the typical case of models with linear-in-parameters utility ...
Mixed modelling of interurban trips by coach and train
(PERGAMON-ELSEVIER SCIENCE LTD, 1998)
A stated preference (SP) experiment for interurban trips by coach or train was designed and programmed on portable computers with the aid of specialized software. Trip characteristics and socio-economic information about ...
Sequential and Simultaneous Estimation of Hybrid Discrete Choice Models Some New Findings
(2010)
The formulation of hybrid discrete choice models, including both observable alternative attributes and latent variables associated with attitudes and perceptions, has become a topic of discussion once more To estimate ...
