This paper analyzes conjoint measurement models allowing for intransitive and/or incomplete preferences. This analysis is based on the study of marginal traces induced on coordinates by the preference relation and uses conditions guaranteeing that these marginal traces are complete. Within the framework of these models, we propose a simple axiomatic characterization of preference relations comp...

The foundational model of conjoint analysis is to model consumer purchase preferences by means of utility functions. Analysts run surveys and interviews to obtain a basic set of training data, typically user preferences on which the utility function is mapped. The utility theory trust the training data as knowledge while there is large literature emphasizing that users preference may change, ma...

Incorporating patients’ preferences into healthcare decisions has been identified as one mechanism for reducing health disparities. Some research suggests that providers need to tailor medical recommendations to the preferences of their patients. Yet there are few tools to facilitate clarification of preferences for health services. This paper reports the process of testing an innovative prefer...

This paper re-examines the discrete choice methods and stated preference elicitation procedures that are commonly used in choice-based conjoint analysis. The aim is to clarify their domains of applicability and provide reliable techniques for data collection and analysis.

OBJECTIVES The purpose of this study was to examine factors influencing occupational therapy students' context-specific attitudes toward persons with disabilities. METHOD Attitudes of 128 occupational therapy students toward placement of a residential treatment facility in their community were measured by a conjoint measurement of 16 stimulus cards (representing persons with varying disabilit...

Young adults have been labelled as one of the most important segments for mobile phones, however there is little empirical evidence to indicate how these young adults value the feature richness of their devices. This research presents a richer view of mobile phone user preferences and perceptions by applying methodologies from the marketing and information systems domains. Conjoint analysis pro...

Suppose that entities composed o f two independent components are qualitatively ordered by a relation that satisfies the axioms o f conjoint measurement. Suppose, i n addition, that each component has a concatenation operation that, together either with the ordering induced on the component by the conjoint ordering or with its converse, satisfies the axioms o f extensive measurement. Without fu...

Depending on the concrete application field and the data collection situation, conjoint experiments can end up with a low internal validity of the estimated part-worth functions. One of the known reasons for this is the (missing) temporal stability and structural reliability of the respondents’ part-worth functions, another reason is the (missing) attentiveness of the respondents in an uncontro...
