The X13 Procedure

Syntax: X13 Procedure

The X13 procedure uses the following statements:

The statements used by PROC X13 perform basically the same function as the Census Bureau’s X-13ARIMA-SEATS specs (specifications). Specs are used in X-13ARIMA-SEATS to control the computations and output. The PROC X13 statement performs some of the same functions as the Series spec in the Census Bureau’s X-13ARIMA-SEATS software. The ADJUST statement performs some of the same functions as the Transform spec. The ARIMA, AUTOMDL, CHECK, ESTIMATE, FORECAST, IDENTIFY, OUTLIER, PICKMDL, REGRESSION, TRANSFORM, and X11 statements are designed to perform the same functions as the corresponding X-13ARIMA-SEATS specs, although full compatibility is not yet available. The Census Bureau documentation X-13ARIMA-SEATS Reference Manual (US Bureau of the Census 2009) provides added insight to the functionality of these statements. The SEATSDECOMP statement is an experimental statement to provide a SEATS (signal extraction in ARIMA time series) seasonal decomposition for the B1 series that uses the same ARIMA model as is used to model the series. For more information about SEATS, see Gómez and Maravall (1997a, 1997b).
