Modification of Moment-Based Tail Index Estimator: Sums versus Maxima
Natalia Markovich, Marijus Vaičiulis · 2017-10-09 · via math.ST updates on arXiv.org

In this paper we continue the investigation of the SRCEN estimator of the extreme value index $γ$ (or the tail index $α=1/γ$) proposed in \cite{MCE} for $γ>1/2$. We propose a new estimator based on the local maximum. This, in fact, is a modification of the SRCEN estimator to the case $γ>0$. We establish the consistency and asymptotic normality of the newly proposed estimator for i.i.d. data. Also, a short discussion on the comparison of the estimators is included.
