Gradient-based bandwidth selection for estimating average derivatives

Abstract

In this paper, we propose to estimate average derivatives of a function by averaging the sample pointwise local linear derivatives with the bandwidth being selected optimally. Our estimator has better finite sample performance than that of Li, Lu & Ullah (2003) because our pointwise derivative estimate reaches the optimal convergence rate. Simulations confirm our theoretical analysis.
