Abstract
A method is proposed for fast selection of bandwidths of kernel functions in the nonparametric estimation of a two-dimensional random variable with dependent components. The method is based on the results of the analysis of the asymptotic properties of the Rosenblatt-Parsen kernel probability density estimation. The properties of a fast algorithm for bandwidth selecting in the considered nonparametric estimation of the probability density are investigated.
