ASYMPTOTIC EXPANSIONS AND BOOTSTRAPPING DISTRIBUTIONS FOR DEPENDENT-VARIABLES - A MARTINGALE APPROACH

The paper develops a one-step triangular array asymptotic expansion for continuous martingales which are asymptotically normal. Mixing conditions are not required, but the quadratic variations of the martingales must satisfy a law of large numbers and a central limit type condition. From this result we derive expansions for the distributions of estimators in asymptotically ergodic differential equation models, and also for the bootstrapping estimators of these distributions.
