Maximum likelihood estimation of mean reverting processes The Ornstein-Uhlenbeck mean reverting (OUMR) model is a Gaussian model well suited for maximum likelihood (ML) methods Alternative methods include least squares (LS) regression of discrete autoregressive versions of the OUMR model and methods of moments (MM)

Ornstein-Uhlenbeck - Imperial College London The basic model for processes of this type is given by the (linear) stochastic differential equation dV = V dt + dW; whose solution is called the Ornstein-Uhlenbeck (velocity) process with re-laxation time 1= and diffusion coefficient D := 1 2= 2
