  • Abstract
    An approximate martingale estimating function with an eigenfunction is proposed for an estimation problem about an unknown drift parameter for a one-dimensional diffusion process with small perturbed parameter ε from discrete time observations at n regularly spaced time points k / n , k = 0 , 1 , … , n . We show asymptotic efficiency of an M -estimator derived from the approximate martingale estimating function as ε → 0 and n → ∞ simultaneously.
