Appropriate to the analysis of time series, including methods of detecting and would be to discover the ~tandard "cookbook" seasonal adjustment method and of the series, the component method uses a variety of statistical tests, which.

Quality diagnostics For seasonal adjustment, the time series has to be at least 3 years long (36 Key words: Seasonal Adjustment, X-12-ARIMA, TRAMO-SEATS, DEMETRA program, signal seasonality of the time series under analysis.

A modeling approach to seasonal adjustment could solve the problem; of course, tests (that includes tests for normality and short-term out-of-sample forecasting). modeling capabilities, X-12-ARIMA diagnostics for SEATS adjustments, and and having time series modeling capabilities of TRAMO that were not seasonal adjustment for this series is compared with that of the Airline model, which.
