Abstract
In this paper, a new kind of location invariant Weiss-Hill estimator of the extreme value index γ ∈ ℝ is proposed. The new estimator is a combination of two estimators proposed by Weiss (Nav Res Logist Q 1:111-114, 1971) and Fraga Alves (Extremes 4:199-217, 2001a). The following properties of the new estimator are derived: weak consistency, strong consistency, and asymptotic expansions. A bias corrected version of the proposed estimator is given after determining an optimal sample fraction. Some finite simulation studies are performed.
