Abstract. We adopt the second order weak Milstein simulation scheme for estimating the true posterior density of diffusions and obtain the rate of weak convergence. We also obtain the Bernstein-von Mises Theorem concerning the convergence of the simulated posterior distribution to normal distribution and asymptotic normality of the Bayes estimator for smooth prior and loss functions.
