- An introduction to Markov modelling for economic evaluationA Briggs
Health Economics Research Centre, Institute of Health Sciences, University of Oxford, England
Pharmacoeconomics 13:397-409. 1998..Analysts should be aware of the limitations of Markov models, particularly the Markovian assumption, although the adept modeller will often find ways around this problem...

Health Economics Research Centre, University of Oxford, Headington, UK
Health Econ 8:257-61. 1999..Although it is argued that their interpretation as the probability that an intervention is cost-effective given the data requires a Bayesian interpretation, this should generate no misgivings for the frequentist...
