Asymptotic Normality of Hill Estimator for Truncated Data
Electronic Journal of Probability, 2011 The problem of estimating the tail index from truncated data is addressed in Chakrabarty and Samorodnitsky (2009). In that paper, a sample based (and hence random) choice of k is suggested, and it is shown that the choice leads to a consistent estimator of the inverse of the tail index.

A Hill Type Estimator of the Weibull Tail-Coefficient [PDF]
Communications in Statistics - Theory and Methods, 2004 We present a new estimator of the Weibull tail-coefficient. The Weibull tail-coefficient is defined as the regular variation coefficient of the inverse cumulative hazard function. Our estimator is based on the log-spacings of the upper order statistics. Therefore, it is very similar to the Hill estimator for the extreme value index.

The generalization of several classical estimators for a positive extreme value index
Modern Stochastics: Theory and ApplicationsIn this paper, we introduce a family of semi-parametric estimators for the positive extreme value index γ, parameterized in two tuning parameters. The asymptotic normality of the introduced estimators is proved. It is shown that the partial case of newly
