A construction of continuous-time ARMA models by iterations of Ornstein-Uhlenbeck processes [PDF]

open access: yes, 2016
We present a construction of a family of continuous-time ARMA processes based on p iterations of the linear operator that maps a Lévy process onto an Ornstein-Uhlenbeck process. The construction resembles the procedure to build an AR(p) from an AR(1). We
