CHANGES IN THIS ISSUE
Each September quarter the reference and base year for chain volume estimates for the Survey of Private New Capital Expenditure are updated. A new base year, 2006-07, has been introduced into the chain volume estimates which has resulted in minor revisions to growth rates in subsequent periods. In addition, the chain volume estimates have been re-referenced to 2006-07. Additivity is preserved in the quarters of the reference year and subsequent quarters. Re-referencing affects the level of, but not the movements in, chain volume estimates.
The Survey of Private New Capital Expenditure uses Autoregressive Integrated Moving Average (ARIMA) modelling where appropriate for seasonal adjustment of individual time series. The ARIMA model is assessed as part of the annual reanalysis which takes place each September quarter. Following the 2008 annual reanalysis which occurred in this quarter, 74% of eligible series use ARIMA modelling. For more information on seasonal adjustment for Survey series in this publication see paragraphs 41 to 43 of the Explanatory Notes.
