Resumo:
This paper intends to perform a comparison of seasonal adjustment procedures. The compared methodologies are X12- ARIMA and TRAMO/SEATS. This current work encompasses the Brazilian Quarterly aggregated accounts which were obtained from the Brazilian Governmental Statistical Office (IBGE - Instituto Brasileiro de Geografia e Estatística) in the period between the first quarter of 1991 and the second quarter of 2000. This data, in the process of analysis, went trough the following software: SPSS, FORECAST PRO, X12-ARIMA (DOS version) and TRAMO/SEATS (DOS version). Some simulated series (with different structures for trend and seasonality) were also used in order to provide further and more accurate comparisons of the two methodologies.
