ABSTRACT:
X-12-ARIMA is the Census Bureau's new seasonal adjustment
program. It provides four types of enhancements to X-11-ARIMA:
- Alternative seasonal, trading day, and holiday effect
adjustment capabilities that include adjustments for effects
estimated with user-defined regressors, additional seasonal and
trend filter options, and an alternative seasonal-trend-irregular
decomposition.
- New diagnostics of the quality and stability of the adjustments
achieved under the options selected.
- Extensive time series modeling and model selection capabilities
for linear regression models with ARIMA errors, with optional
robust estimation of coefficients.
- A new user interface with features to facilitate batch
processing large numbers of series.
