Arima 1 2 1

Web1 Answer. The simple reason is the random component. You fitted an ARMA (2,1) model but due to the random variable in every step, it is possible that this random factor ensure that the ARMA (2,1) model looks like an ARMA (1,1) model. This can happen and in another seed the AIC and BIC might select an ARIMA (1,2) as the best model fit and even ... WebARIMA(1,1,1) Model. A time series modelled using an ARIMA(1,1,1) model is assumed to be generated as a linear function of the last 1 value and the last 1+1 random shocks generated. The data is different 1 time. Differencing the model once does not make it stationary enough for the ARIMA model. Hence, we shall try ARIMA(2,2,1). …
