  • Modelling and Inference for Extremal Events 

    Sun, Julian (2018-08-11)
    Extreme events are frequently observed in nature and in human activities; they tend to have severe and often negative impact. For this reason they are wellstudied, and the underlying body of work is usually referred to ...
  • Regularly Varying Random Fields 

    Wu, Lifan; Samorodnitsky, Gennady (2019-09-05)
    We study the extremes of multivariate regularly varying random fields. The crucial tools in our study are the tail field and the spectral field, notions that extend the tail and spectral processes of Basrak and Segers ...
  • Distance covariance for discretized stochastic processes 

    Dehling, Harold; Matsui, Muneya; Mikosch, Thomas; Samorodnitsky, Gennady; Tafakori, Laleh (2018-06-26)
    Given an iid sequence of pairs of stochastic processes on the unit interval we construct a measure of independence for the components of the pairs. We define distance covariance and distance correlation based on ...
  • From infinite urn schemes to self-similar stable processes 

    Durieu, Olivier; Samorodnitsky, Gennady; Wang, Yizao (2017)
    We investigate the randomized Karlin model with parameter beta in (0,1), which is based on an infinite urn scheme. It has been shown before that when the randomization is bounded, the so-called odd-occupancy process scales ...
  • Extreme value analysis without the largest values: what can be done? 

    Zou, Jingjing; Davis, Richard; Samorodnitsky, Gennady (2017)
    In this paper we are concerned with the analysis of heavy-tailed data when a portion of the extreme values are unavailable. This research was motivated by an analysis of the degree distributions in a large social network. ...
