So i got two different data sets that I want to put together, one is from 2004-05 to 2014-15 with the base year 2004-05 and the other one is 2011-12 to 2021-22 with base year 2011-12. I have also found the WPI index for both 2004-05 and 2011-12 that they are using.
I would like to use an WPI index that cover all of these years so I could put these two series together. I hope one of you guys knows how I should proceed! Many thanks.
