In spatial statistics, fast and accurate parameter estimation, coupled with a reliable means of uncertainty quantification, can be challenging when fitting a spatial process to real-world …
Regular vine sequences permit the organization of variables in a random vector along a sequence of trees. Vine-based dependence models have become greatly popular as a way …
We show how to perform full likelihood inference for max‐stable multivariate distributions or processes based on a stochastic expectation–maximization algorithm, which combines …

This paper considers the specification of covariance structures with tail estimates. We focus on two aspects:(i) the estimation of the VaR-CoVaR risk matrix in the case of larger number …
Statistical modeling of multivariate and spatial extreme events has attracted broad attention in various areas of science. Max-stable distributions and processes are the natural class of …
The Supplementary Material (Lalancette, Engelke and Volgushev (2021)) is divided into six sections. Section S1 contains the proofs of all main results, with a number of necessary …
E Koch, CY Robert - European Journal of Operational Research, 2022 - Elsevier
We consider expected performances based on max-stable random fields and we are interested in their derivatives with respect to the spatial dependence parameters of those …
J Blanchet, Z Liu - Monte Carlo and Quasi-Monte Carlo Methods: MCQMC …, 2018 - Springer
We introduce a class of unbiased Monte Carlo estimators for multivariate densities of max- stable fields generated by Gaussian processes. Our estimators take advantage of recent …
