Bulletin of the International Statistical Institute, Lisboa, 2007.978-972-673-992-0AUT: LNF01492; LMP01693;http://hdl.handle.net/10400.1/904The use of preference-based measures of health in the measurement of Health Related Quality of Life has become widely used in health economics. Hence, the development of preference-based measures of health has been a major concern for researchers throughout the world. This study aims to model health state preference data using a new preference-based measure of health (the SF- 6D) and to suggest alternative models for predicting health state utilities using fixed and random effects models. It also seeks to investigate the problems found in the SF-6D and to suggest eventual changes to it.engHealth state preferencesHealth state utilitiesSF-6Dconference object2012-02-18
