WebNov 13, 2015 · We study an Horvitz-Thompson version of the Hill estimator in the framework of survey sampling. We follow the approach of Bertail, Chautru and Clémençon (2013) to study the asymptotic normality of this estimator. We first etablish its asymptotic properties for the Poisson survey sampling plan (with unequal probabilities) in the spirit of ...
