CHANGES IN FORTHCOMING ISSUES
IMPROVEMENT TO SEASONAL ADJUSTMENT METHOD OF CURRENT PRICE VALUES OF METAL ORES AND MINERALS AND OF OTHER MINERAL FUELS
An improvement will be applied to the seasonal adjustment method of current price goods credits components 'metal, ores and minerals' and 'other mineral fuels'. For the quarterly series (included in Balance of Payments and International Investment Position, Australia (cat. no. 5302.0)) from September quarter 2005 onwards, seasonal factors derived from the corresponding chain volume measures will be applied to seasonally adjust the current price values. For the monthly series, although chain volume measures are not available on a monthly basis, a similar method will be used to seasonally adjust the monthly current price value series from July 2005 onwards. As a result of this improvement, trend break corrections previously applied to the 'metal ores and minerals' trend series will be removed. This improvement will be implemented from the March 2017 issue of this publication and the March quarter 2017 issue of the Balance of Payments and International Investment Position, Australia (cat. no. 5302.0) publication.
