What If...? Revisions to Trend Estimates
Effect of new seasonally adjusted estimates on trend estimates
SENSITIVITY ANALYSIS
Readers should exercise care when interpreting the trend estimates of recent months because they will be revised when next month’s seasonally adjusted estimates become available. For further information, see paragraphs 21 to 22 in the Explanatory Notes.
The graph below presents the effect of two possible scenarios on the previous trend estimates:
1 The March 2004 seasonally adjusted estimate of number of dwellings financed is higher than the February 2004 seasonally adjusted estimate by 4.0%.
2 The March 2004 seasonally adjusted estimate of number of dwellings financed is lower than the February 2004 seasonally adjusted estimate by 4.0%.
The percentage change of 4.0% was chosen because the average absolute percentage change of the seasonally adjusted series, based on the last 10 years of data, has been 4.0%.
