After introducing the fundamental concepts, we examined the construction and asymptotic roperties of the maximum likelihood estimator. This theory was applied to the Ornstein-Uhlenbeck process, where we verified the regularity conditions and performed numerical simulations to illustrate the theoretical study.frThesis
