In the original paper, the Ornstein-Uhlenbeck process is used, which is adapted for physical control problems with inertia. 5) or mean reverting (H < 0. In a nutshell, this nifty little number H tells us if a time series is a random walk (H ~ 0. The other tool we used previously to determine a mean reverting series is the hurst Exponent. Function coinT() tests if two time series are stationary using ADF test and Hurst exponent.
