Changes to model inputs

Inputs to the Moody's Analytics forecast models encompass both historical verbatim datasets and Moody's Analytics historical estimates. Changes originate at the source (revision or redefinition), our choice of inputs (source entity, specific indicator, or variant of an indicator), and our pre-processing of inputs (frequency conversion, etc.).

We may construct estimates as an interim solution when a source does not report in a convenient analytic form, but always prefer to use a source verbatim. A change from a cross-national source to a national source improves timeliness, transparency and consistency, unless otherwise noted.

In the table below, when a country name is marked (*), the change flows from a single country into relevant regional aggregates. The abbreviations "NCB" and "NSI" refer to the national central bank and national statistical institute of each country, respectively. The abbreviation "n.o.s." means "not otherwise stated".

Changes to methodology

For multinational stock price indexes (for example, FSTOCKPQ.IWRLD), we have inserted a step to convert each component national index to USD terms, prior to aggregation.
