Bandwidth matrix selectors for multivariate kernel density estimation

Multivariate kernel density estimators have become a common tool for empirical studies. These estimators depend on the choice of a crucial parameter -- the bandwidth matrix. In this paper, we propose an extension of the iterative me...

Iterative method for kernel density estimates ? small sample properties

Kernel density estimates belong to the class of the nonparametric density estimates. These estimates depend on a bandwidth matrix which affects the amount and the orientation of the smoothing. We focus on the iterative meth...
