Webb1 apr. 2024 · There is no finite dimensional parametric family for the Pickands dependence function to guide the choice of dependence function. Nevertheless, the existing literature presents various parametric and nonparametric dependence function estimators [see section 9.3 of Beirlant et al. (2006) for a review]. Webb20 juli 2024 · In this study, a new nonparametric approach using Bernstein copula approximation is proposed to estimate Pickands dependence function. New data points …
