Admisibilidad de la estimación equivariante

Abstract

En este trabajo se plantea el problema de la admisibilidad, resaltando algunos de los principales resultados teóricos sobre la admisibilidad cuando la función de pérdida es cuadrática, y recogiendo los resultados de Katz en espacios truncados bajo pérdida cuadrática. A continuación nos fijamos en dos tipos particulares de estimadores: los Equivariantes y el de Pitman, para terminar discutiendo su admisibilidad.

In this paper we raise the problem of admisibility emphasizing some of the most outstanding theoretical results on admisibility when the loss function is quadratic, according to Katz's results on truncated spaces under quadratic loss. Next we foms our attention in two specific types of estimators: Equivariants and Pitman, to end up discussing their admisibility.
