Gauss–Markov stochastic processes (named after Carl Friedrich Gauss and Andrey Markov) are that satisfy the requirements for both Gaussian processes and Markov processes. The stationary Gauss–Markov process (also known as a Ornstein–Uhlenbeck process) is a very special case because it is unique, except for some trivial exceptions.
Every Gauss–Markov process X(t) possesses the three following properties:
Property (3) means that every Gauss–Markov process can be synthesized from the standard Wiener process (SWP).
A stationary Gauss–Markov process with variance and time constant has the following properties.
