Cross-validation in density estimation
Department of Statistics, Faculty of Economics, Australian National University Canberra, Australia
We examine the cross-validatory method of choosing the window size when estimating a density on a bounded interval. Tt is shown that even if the resulting estimator is consistent it will perform suboptimally for large samples, and should be used cautiously. Alternative techniques, such as that proposed by Silverman (1978a), would be a wiser choice.
