In Macrobond you can create index in two ways:
1. If your purpose is only to scale series to start at a specific value, like 100, then the Rebase analysis should be used.
You’ll find more information on using the Rebase analysis here.
2. The Index Builder analysis can be used to create indices that measure self-financing investment strategy returns, as well as indices built as weighted averages of a number of series.
There are several calculation methods to choose from – for more details please refer to this article.
