Analyzing the continuity of attitudinal and perceptual indicators in hybrid choice models

Francisco J. Bahamonde-Birke and Juan de Dios Ortúzar

Journal of choice modelling, 2017, vol. 25, issue C, 28-39

Abstract: The main objective of this paper is to compare the consequences of treating the attitudinal and perceptual indicators of hybrid discrete choice (HDC) models as continuous or ordinal outcomes. Based on tradition and computational reasons, such indicators are still predominantly treated as continuous outcomes in practice. This usually neglects their nature (as respondents are normally asked to state their preferences, or level of agreement with a set of statements, using a discrete scale) and may induce bias.
