关于O-U过程的一个注记
A Note on Ornstein-Uhlenbeck Process
-
摘要: 对于O-U过程, 我们证明了: 如果经典的Kalman条件不满足,那么经过一个可逆的线性变换, 该O-U过程可以分解为一个随机过程和一个确定性过程.Abstract: For the Ornstein-Uhlenbeck process, we prove that if the classical Kalman's condition doesn't hold, then it can be divided into a deterministic process plus a stochastic process after a linear and invertible transformation.
