Some explanations on the new revision policy: current[AO]

The new revision policy fixes the model (including all the parameters) and handle any new observation as an additive outlier. Those “pseudo outliers” are in fact introduced in the model as intervention variables (to avoid possible confusion).

It is easy to show that, in the case of model-based decompositions (canonical decomposition, structural model…), this solution is exactly the same as using forecasts (some small discrepancies can appear, due for instance to the bias correction in multiplicative models). In X13, that approach is not exactly the same as the use of forecasts, due to the fact that the projected seasonal factors are not necessary coherent with the ARIMA forecasts. In most cases, the differences between the use of “Current[AO]” and “Current[forecasts]” are small.

The main advantages of the “Current[AO]” approach are:

  • No modification of usual routines
  • Usual diagnostics (+ estimation of the size of the AO)
  • Possibility to fine tune the model (removal of some “AO”…)

The generated intervention variables are kept in the model (and perhaps re-estimated) when other revision policies are applied on subsequent periods, except in the case of the concurrent (=complete) policy; in that latter case they are removed from the model. Statisticians must then decide on the best handling of the series (use of automatic outliers detection, of ramps, of specific regression variables…)
