With the G.17 statistical release on April 18, 2017, the Federal Reserve Board began publishing estimates of the reliability of the levels and the rates of change (monthly and quarterly) of the reported production indexes for total industry, manufacturing, mining, and utilities. The reliability estimates are designed to give data users a sense of the typical range into which a statistic will likely end up after its final (fifth) revision in a monthly release. The reliability estimates are based on the revision history for the indexes back to 2008; each G.17 release will include estimates for those months and quarters for which either new or updated estimates were issued that month. A detailed explanation is available on the Board’s website at https://www.federalreserve.gov/releases/g17/revisions/Current/DefaultRev.htm.
The reliability estimates are issued in table 15 of the G.17 release, available on the Board’s website at https://www.federalreserve.gov/releases/g17/20170418/default.htm. A text file that contains the estimates is also available on the Federal Reserve’s website at https://www.federalreserve.gov/releases/g17/ipdisk/revh_sa.txt.
