Recommended Statistical Measures for Interpreting the Outputs of Revision Analyses


Back to OECD / Eurostat guidelines on revisions policy and analysis


This document presents recommendations developed by the task-force on statistical measures for interpreting the outputs of revisions analyses for economic variables published on a monthly or quarterly frequency.  The key issues this document attempts to address in regards to the various summary statistics that can be calculated when performing a revisions analysis are:

• What question about revisions to the economic variable does the summary statistic answer?

• What type of user does the summary statistic target?


The recommended statistical measures have been built into the pre-programmed software for performing revisions analysis also developed by the task-force.
