Abstract

The density of a sum of independent random variables can be estimated by the convolution of kernel estimators for the marginal densities. We show under mild conditions that the resulting estimator is n1/2-consistent and converges in distribution in the spaces C0(Ropf) and L1 to a centered Gaussian process.
Keywords: Plug-in estimator; Kernel density estimator; Parametric convergence rate; von Mises statistic; Functional central limit theorem
