Modelling An O-U Process In order to model the O-U process on a computer (for example using Matlab), it is usual to discretize.
On the Simulation and Estimation of the Mean-Reverting Ornstein-Uhlenbeck Process. Why is this important? If we enter into a mean-reverting position, and 3 or 4 half-life’s later the spread still has not reverted to zero, we have reason to believe that maybe the regime has changed, and our mean-reverting model may not be valid anymore. ref.Mean reversion is a financial term for the assumption that a stock's price will tend to move to the average price over time.
