On the residual dependence index of elliptical distributions
收藏 引用
STATISTICS & PROBABILITY LETTERS 2010年 第13-14期80卷 1070-1078页
作者: Hashorva, Enkelejd Univ Bern Dept Math Stat & Actuarial Sci CH-3012 Bern Switzerland
The residual dependence index of bivariate Gaussian distributions is determined by the correlation coefficient. This tail index is of certain statistical importance when extremes and related rare events of bivariate s... 详细信息
