Improving precision in cost-effectiveness analysis using copulas.
Quinn, Casey - Department of Economics and Related Studies, University … - 2007
A copula is best described, as in Joe (1997), as a multivariate distribution function that is used to bind each marginal distribution function to form the joint. The copula parameterises the dependence between the margins, while the parameters of each marginal distribution function can be...

Using copulas to estimate reduced-form systems of equations
Quinn, Casey - Department of Economics and Related Studies, University … - 2007
This paper introduces a new approach to measuring the association between health and socioeconomic status. Measuring inequalities in health is difficult when health is measured qualitatively, specifically on an ordinal scale. This paper demonstrates a rank-based dependence measure - the copula -...
