AUGUST KEY FIGURES
This publication presents statistics on livestock slaughterings and meat production. These statistics are based on a monthly collection from abattoirs and other major slaughtering establishments. More detailed information on this series can be obtained by contacting the ABS or by referring to the quarterly ABS publication Livestock Products, Australia (cat. no. 7215.0).
The September 2007 issue of this data is due for release on 1 November 2007.
For more information about these and related statistics, contact Nigel Gibson on Hobart (03) 6222 5940, or the National Information and Referral Service on 1300 135 070.
Annual seasonal adjustment reanalysis: The annual reanalysis of the quarterly livestock products collection will be undertaken after the release of this issue. Any revisions to the seasonally adjusted and trend estimates series will be incorporated with the release of September 2007 monthly data.
Introduction of ARIMA modelling techniques: In recent years, the ABS has implemented improved methods of producing seasonally adjusted estimates, focused on the application of Autoregressive Integrated Moving Average (ARIMA) modelling techniques. The revision properties of the seasonally adjusted and trend estimates can be improved by the use of ARIMA modelling. ARIMA modelling relies on the characteristics of the series being analysed to project future period data. The projected values are temporary, intermediate values, that are only used internally to improve the estimation of the seasonal factors. The projected data do not affect the original estimates and are discarded at the end of the seasonal adjustment process.
The Livestock Products collection will use, from the 2007 annual seasonal reanalysis, concurrent seasonal adjustment with ARIMA modelling where applicable to reduce the level of revision to the seasonally adjusted livestock products estimates. For more information about ARIMA modelling, refer to 'Feature article: Use of ARIMA modelling to reduce revisions' in the October 2004 issue of Australian Economic Indicators (cat. no. 1350.0).
These documents will be presented in a new window.
