主题：Testing the multivariate regular variation model
主讲人：Associate Prof. Chen Zhou Erasmus University Rotterdam and De Nederlandsche Bank (荷兰)
简介：Chen Zhou is associate professor of statistics at the Erasmus University Rotterdam and seminar economist at De Nederlandsche Bank (荷兰中央银行). His main research interests are in extreme value statistics and its applications in risk management. Chen has published in various top journals of statistics and finance. Chen is the associate editor of Extremes.
摘要：In this paper, we propose a test for the multivariate regular variation model. The test is based on testing whether the extreme value indices of the radial component conditional on the angular component falling in different subsets are at the same level. Combining the test on the constancy across different conditional extreme value indices with testing the regular variation of the radial component, we obtain the test for testing multivariate regular variation. Simulations and applications are studied.
