Abstract
Choice models are becoming increasingly useful for soliciting and analyzing multiple objective decisions faced by recreation managers and others interested in decisions involving natural resources. Choice models are used to estimate relative values for multiple aspects of natural resource management, not individually but within the context of other relevant decision attributes. They are especially useful for understanding and evaluating acceptable tradeoffs for decision attributes that do not have market prices. Choice models often use a paired-comparison dichotomous choice format for soliciting preferences from stakeholders. We explore the use and analytics involved in incorporating a strength-of-preference scale within this format. An ordered logit model that includes a strength-of-preference scale is compared to a commonly used dichotomous choice logit specification. A case study of back country wilderness users in Yosemite National Park is used as an illustrative example.
