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…

Applying different methods to model dry and wet spells at daily scale in a large range of rainfall regimes across Europe
Giorgio Baiamonte, Carmelo Agnese, Carmelo Cammalleri +3
The modelling of the occurrence of rainfall dry and wet spells (ds and ws, respectively) can be jointly conveyed using the inter-arrival times (it). While the modelling of it has t…

Orthogonal gamma-based expansion for the CIR's first passage time distribution
Elvira Di Nardo, Giuseppe D'Onofrio, Tommaso Martini
In this paper we analyze a method for approximating the first-passage time density and the corresponding distribution function for a CIR process. This approximation is obtained by…
