WebIl modello ARMA (acronimo di Autoregressive Moving Average, «autoregressivo e a media mobile») estende il modello autoregressivo considerandone gli errori come serialmente correlati. Formalmente si dice che una serie storica y t segue un modello ARMA ( p, q) se soddisfa la relazione: y t = a0 + a1 y t−1 +...+ apyt − p + εt , dove εt WebDescription.
