This IFs Base Comparison process relates to the consolidation of big data update. It is usually conducted once a year during the big data update.

Top-down approach:
Top down approach implies using all new updated data to build a new base and comparing with old/existing base. After few observations, we can replace few new series by old series to see the impact of addition of those new series. This page follows this approach.

Bottom-up approach:
It is the opposite of top-down approach. This allows us to add new series one at a time and see its impact.

Things to do first before IFs Base Comparison:

  1. Rebuilding Base
    1. See Rebuild Base Notes for this specific task
    2. See more on rebuilding the base here
  2. Variable names
    1. Variable names to compare model are in “Variable_names_8142020.txt”
  3.
