X-11-ARIMA and X-12-ARIMA propose different models for correcting the Easter effect based on an estimate of the irregular component. The proposed models and the methods used are sometimes quite different in the two softwares, which is why we have not integrated them directly into the seasonal adjustment example of Chapter 4.
