The empirical discrete copula process
Gery Geenens, Ivan Kojadinovic, Tommaso Martini
This paper develops a general inferential framework for discrete copulas on finite supports in any dimension. The copula of a multivariate discrete distribution is defined as Csisz…

On the differentiability of -projections in the discrete finite case
Gery Geenens, Ivan Kojadinovic, Tommaso Martini
In the case of finite measures on finite spaces, we state conditions under which Ï- projections are continuously differentiable. When the set on which one wishes to Ï- project is…
