Arma arima
WebThe autoregressive moving average model (ARMA), autoregressive integrated moving average model (ARIMA) and the seasonal autoregressive integrated moving average model (SARIMA) are also commonly used models in time series analysis. Evidently, they all come from the same family. Thus, we will explain the small differences between them. WebARMA/ARIMA, modelli di Samantha Leorato Il modello ARMA (acronimo di Autoregressive Moving Average, «autoregressivo e a media mobile») estende il modello autoregressivo considerandone gli errori come serialmente correlati.
