New seasonal adjustment method CAMPLET eliminates need for revisions, improving accuracy.
Seasonal adjustment methods like X-13ARIMA-SEATS and CAMPLET help remove seasonal patterns from economic data for better analysis. CAMPLET separates seasonal and non-seasonal components without needing revisions later on, unlike other methods. The study compared X-13ARIMA-SEATS and CAMPLET using simulations and real data like U.S. employment and GDP in the Netherlands.
