Estimation for Discretely Observed Small Diffusions Based on Approximate Martingale Estimating Functions

Abstract

. We consider an asymptotically efficient estimator of the drift parameter for a multi‐dimensional diffusion process with small dispersion parameter ɛ. In the situation where the sample path is observed at equidistant times k/n, k = 0, 1, …, n, we study asymptotic properties of an M‐estimator derived from an approximate martingale estimating function as ɛ tends to 0 and n tends to ∞ simultaneously.
