Copulas and the Information Management

Naoyuki Ishimura, Ting Li, and Masa Aki Nakamura
Abstract— Copula is introduced as a tool for understanding the dependence structure among random variables. Copulas make a link between multivariate joint distributions and univariate marginal distributions, and provide a flexible way to describe nonlinear dependence; copulas therefore have been applied in many fields. Here we deal with a family of generalized Archimedean (GA) copulas. In terms of these GA copulas, we derive the formula for the Kendall’s tau, which is a well known measure of concordance. Applications to the management are discussed.

Index Terms— Copula, (generalized) Archimedean copula, Kendall’s tau, information management.
