Document Details : Title: Measuring Comonotonicity in M-Dimensional Vectors Author(s): KOCH, Inge , DE SCHEPPER, Ann Journal: ASTIN Bulletin Volume: 41 Issue: 1 Date: 2011 Pages: 191-213 DOI: 10.2143/AST.41.1.2084391 Abstract : In this contribution, a new measure of comonotonicity for m-dimensional vectors is introduced, with values between zero, representing the independent situation, and one, reflecting a completely comonotonic situation. The main characteristics of this coefficient are examined, and the relations with common dependence measures are analysed. A sample-based version of the comonotonicity coefficient is also derived. Special attention is paid to the explanation of the accuracy of the convex order bound method of Goovaerts, Dhaene et al. in the case of cash flows with Gaussian discounting processes. |
