WebHi there, according to this link, the estimation of half life from an AR (1) process should instead be log (0.5)/log (numpy.abs (res.params [1])). This derivation is typical from the ARMA methods. from OU process, have the result of log 2 / α where α > 0 is the speed of mean reversion. mathtopics.wordpress.com/2013/01/10/… – WillZ WebThis gives the process its informative name, "mean-reverting." Properties of sample paths [ edit] A temporally homogeneous Ornstein–Uhlenbeck process can be represented as a scaled, time-transformed Wiener process : where is the standard Wiener process. This is roughly Theorem 1.2 in Doob 1942. Equivalently, with the change of variable this becomes WebI have mean reverting data (Difference of 2 stock prices, that I want to do pairs trading on).
