Abstract
Recent investigations about notions of bivariate aging have underlined the need to introduce some new properties of positive dependence for a bivariate random vector. Here, by using the recent notion of supermigrativity of a bivariate copula, a positive dependence property is introduced and investigated. Comparisons with other notions of positive dependence are also presented.File in questo prodotto:
