Ab. Tsybakov et Ec. Vandermeulen, ROOT-N CONSISTENT ESTIMATORS OF ENTROPY FOR DENSITIES WITH UNBOUNDED SUPPORT, Scandinavian journal of statistics, 23(1), 1996, pp. 75-83
We consider a truncated version of the entropy estimator proposed by K
ozachenko & Leonenko (1987) and based on spacings of order 1. We prove
the mean square root n-consistency of the estimator for a class of de
nsities with unbounded support, including the Gaussian density.
