%A Jeffrey Hart %A Philippe Vieu %J The Annals of Statistics %T Data-Driven Bandwidth Choice for Density Estimation Based on Dependent Data %X The bandwidth selection problem in kernel density estimation is investigated in situations where the observed data are dependent. The classical leave-out technique is extended, and thereby a class of cross-validated bandwidths is defined. These bandwidths are shown to be asymptotically optimal under a strong mixing condition. The leave-one out, or ordinary, form of cross-validation remains asymptotically optimal under the dependence model considered. However, a simulation study shows that when the data are strongly enough correlated, the ordinary version of cross-validation can be improved upon in finite-sized samples. %N 2 %P 873-890 %V 18 %D 1990 %I Institute of Mathematical Statistics %R doi:10.1214/aos/1176347630 %L epos227
