Abstract
In statistics of extremes, the estimation of the extreme value index (EVI) is an important and central topic of research. We consider the probability weighted moment estimator of the EVI, based on the largest observations. Due to the specificity of the properties of the estimator, a direct estimation of the threshold is not straightforward. In this work, we consider an adaptive choice of the number of order statistics based on the double bootstrap methodology. Computational and empirical properties of the methodology are here provided.
