Now that we are more or less familiar with the idea of ARIMA models, we can move to practicalities. As it might become apparent from the previous sections, one of the issues with the model is the identification of orders p, d, q, P \(_j\), D \(_j\), Q \(_j\) etc. Back in the 20th century, when computers were slow, this was a …
WebBox-Jenkins Model Identification Stationarity and Seasonality The first step in developing a Box-Jenkins model is to determine if the series is stationary and if there is any significant seasonality that needs to be modeled. Detecting stationarity Stationarity can be assessed from a run sequence plot .
