The ornstein-uhlenbeck process
In mathematics, the Ornstein–Uhlenbeck process is a stochastic process with applications in financial mathematics and the physical sciences. Its original application in physics was as a model for the velocity of a massive Brownian particle under the influence of friction. It is named after Leonard Ornstein … Visa mer Conditioned on a particular value of $${\displaystyle x_{0}}$$, the mean is $${\displaystyle \operatorname {\mathbb {E} } (x_{t}\mid x_{0})=x_{0}e^{-\theta t}+\mu (1-e^{-\theta t})}$$ and the Visa mer Noisy relaxation The Ornstein–Uhlenbeck process is a prototype of a noisy relaxation process.
