Discrete choice experiment validation: A resource project case study

It is necessary to validate discrete choice experiments to ensure they will lead to reasonable responses and, consequently, to valid modeling results. While some researchers have started to consider the validity of their discrete choice experiments, the approaches used for such validation are not widely reported in the literature. This paper addresses the validation process, which is crucial to the integrity of discrete choice experiments. In particular, this study addresses the selection of attributes and levels, as well as the cognitive load imposed on respondents.
