Rebase to a Previous Index
- Value in current index/100)*value of rebase year in previous index eg)
- In 2006, a commodity had an index score of 111 based on the rebased value in 2001
- The value in 2001 of the commodity was 132 in the old index (now 100, since it is the new base year)
- To express 2006 in terms of the previous index base:
- (111/100) *132 = 146.52
