Bias-corrected geometric-type estimators of the tail index

Margarida Brito; Laura Cavalcante; Ana Cristina Moreira Freitas

The estimation of the tail index is a central topic in extreme value analysis. We consider a geometric-type estimator for the tail index and study its asymptotic properties. We propose here two asymptotic equivalent bias-corrected geometric-type estimators and establish the corresponding asymptotic behaviour. We also apply the suggested estimators to construct asymptotic confidence intervals for this tail param...
