Assume that the distribution of $X_{z}$ has a density function $f(x)$ . Fix an observation-domain $V¥subset R^{d}$ . Suppose that we are to estimate the value $f(x)$ using the data observed on V. lf the data are given as observations at counting points of $N(dz)$ , then the following kernel density estimator is natural: $f_{V}(x)=(N(V)h_{N(V)})^{-1}¥int_{V}K((x-X_{z})/h_{N(V)})N(dz)$ where $h_{n}$ is a band-width parameter. In this paper we discuss the central limit theorem and the convergence rate of the bias and the mean square error for $f_{V}(x)$ as the volume $|V|$ tends to $¥infty$ . In addition, we shall refer to the estimations of joint probability density functions.}, pages = {127--152}, title = {NONPARAMETRIC DENSITY ESTIMATIONS FOR A CLASS OF MARKED POINT PROCESSES}, volume = {41}, year = {1994} }
