Tail Index Regression

Journal of the American Statistical Association, 2009
In extreme value statistics, the tail index is an important measure to gauge the heavy-tailed behavior of a distribution. Under Pareto-type distributions, we employ the logarithmic function to link the tail index to the linear predictor induced by covariates, which constitutes the tail index regression model.

Asymptotic Expansions of Estimators for the Tail Index with Applications

Scandinavian Journal of Statistics, 1998
We present asymptotic expansions for two well‐known estimators of the tail index of a distribution—the Hill's estimator and the simplified Pickands' estimator. We then use the expansions to get more accurate interval estimates. Comparisons between the two estimators are also discussed.

A Class of Tests on the Tail Index

Extremes, 2001
For the i.i.d. sample with d.f. \(F(x)\) a nonparametric test is proposed for the null hypothesis \(H_m:\;x^m(1-F(x))\geq 1\quad\forall x>x_0\) for some \(x_0>0\) with a given \(m>0\), against the alternative \(K_m:\lim\sup_{x\to\infty} x^m(1-F(x))
