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 30 and 31 in the Explanatory Notes.

The graph below presents the effect of two possible scenarios on the trend estimates:

1 The January 2010 seasonally adjusted estimate of the number of dwelling commitments is higher than the December 2009 seasonally adjusted estimate by 2.3%.

2 The January 2010 seasonally adjusted estimate of the number of dwelling commitments is lower than the December 2009 seasonally adjusted estimate by 2.3%.

The percentage change chosen is the average absolute percentage change of the seasonally adjusted series, based on the last 10 years of data.
