J. Beirlant et L. Gyorfi, ON THE L-1-ERROR IN HISTOGRAM DENSITY-ESTIMATION - THE MULTIDIMENSIONAL CASE, Journal of nonparametric statistics, 9(2), 1998, pp. 197-216
Under some smoothness and tail conditions on the density the rate of c
onvergence of the expected L-1-error of the classical histogram densit
y estimator is calculated in any dimension. The asymptotic distributio
n of the standardized L-1-error is derived under minimal conditions. I
n particular, a sharp uniform rate for the variance of the error is es
tablished and explicit representations of the asymptotic variance of t
he error are given.
