Multiattribute-revealed preference data are used to investigate heterogeneity in a sample of kayakers for a panel of whitewater sites in Ireland. This article focuses on a comparison of preference heterogeneity using a random parameter logit model wi...

Design efficiency for non-market valuation with choice modelling: how to measure it, what to report and why. (2008)
Journal Article
Scarpa, R., & Rose, J. (2008). Design efficiency for non-market valuation with choice modelling: how to measure it, what to report and why. The Australian Journal of Agricultural and Resource Economics, 52(3), 253-282. https://doi.org/10.1111/j.1467-8489.2007.00436.x

We review the basic principles for the evaluation of design efficiency in discrete choice modelling with a focus on efficiency of WTP estimates from the multinomial logit model. The discussion is developed under the realistic assumption that research...
