Abstract. Given a sequence of independent random variables with density f we estimate quantities theta of the form theta = \int phi(f(x))dx, phi a known function, by inserting histograms and kernel density estimators for the unknown f. We obtain conditions for consistency and asymptotic normality and discuss the choice of cell size and bandwidth.
Key words and phrases: Density functionals, empirical central limit theorem, estimation.
