gremes (version 0.1.1)

Estimation of Tail Dependence in Graphical Models

Description

Provides tools for estimation of edge weights on graphical models with respect to trees and block graphs and parameterized by a particular family of max-stable copulas. The edge weights are parameters of tail dependence between adjacent variables and these edge weights determine the joint tail dependence between all variables in the context of a particular parametric model. For methods of moment estimator, composite likelihood estimator please see Asenova et al. (2021) . For estimation based on extremal coefficients see Asenova et al. (2021) as well as Einmahl et al. (2016) . For cliquewise estimation please see Engelke and Hitz (2020) .
