Abstract:	In collaboration with the current developers of the SEATS seasonal adjustment program, an experimental version of X-12-ARIMA that produces model-based seasonal adjustments from SEATS has recently been made available to users. This program allows users of seasonally adjusted series to generate X-11 and SEATS sesonal adjustments using the same interface, and compare these seasonal adjustments using a common set of diagnostics. This session will demonstrate how SEATS adjustments are integrated into the X-12-ARIMA procedure and give examples of new modeling options such as seasonal outliers and pulse regressors.
