The stochastic approximation method for recursive kernel estimation of the conditional extreme value index
Résumé
In this research paper, our central focus is upon applying the stochastic approximation method to define a class of recursive kernel estimator of the conditional extreme value index. We investigate the properties of the proposed recursive estimator and compare them to those pertaining to Hill's non-recursive kernel estimator. We attempt to demonstrate that using some optimal parameters, the proposed recursive estimator defined by the stochastic approximation algorithm proves to be very competitive to Hill's non-recursive kernel estimator. Finally, the theoretical results are explored through simulation experiments and illustrated using real dataset about Malaria in Senegalese children.
