報告摘要:
In this talk, we investigate the asymptotic properties of an ergodic Ornstein-Uhlenbeck process with jumps driven by a standard Brownian motion and an independent compensated compound Poisson process. Employing an explicit approach based on Poisson Wiener-It\^o chaos decompositions, we first establish deviation inequalities and moderate deviations for the integral functionals of the Ornstein–Uhlenbeck process. Subsequently, by combining these limit theorems with tools from asymptotic analysis, we derive strong consistency, asymptotic normality and (Cram\'er-type) moderate deviation results for the least squared estimators of the drift coefficient.
