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 one new series at a time and observe its impact.
Things to do first before IFs Base Comparison:
- Rebuilding Base
- See Rebuild Base Notes for this specific task
- See more on rebuilding the base here
- Variable names
- Variable names to compare model are in “Variable_names_8142020.txt”
