Abstract
Using Malliavin calculus along with Stein’s equation, the chapter shows that the distribution of the maximum likelihood estimator of the drift parameter in the Pearson diffusion process observed over [0, T] converges to the standard normal distribution with an uniform error rate of the order O(T −1∕2). Then based on discrete observations, it obtains martingale estimation function estimators and studies their rate of weak convergence to normal distribution.
