2011, v.17, Issue 1, 119-150


One obtains the Ornstein - Uhlenbeck - Gamma process when the Brownian component of the Ornstein - Uhlenbeck process is contaminated by a Gamma process. The paper introduces some new estimators of the drift parameter in the Ornstein - Uhlenbeck - Gamma process based on discretely sampled data and obtains rates of weak convergence of the distributions of the estimators to the standard normal distribution using random, nonrandom and mixed normings.
