Release: Brave-Butters-Kelley Indexes
The Brave-Butters-Kelley Indexes (BBKI) are a research project of the Federal Reserve Bank of Chicago. The BBK Coincident and Leading Indexes and Monthly GDP Growth for the U.S. are constructed from a collapsed dynamic factor analysis of a panel of 500 monthly measures of real economic activity and quarterly real GDP growth.
The irregular component of GDP is expressed in annualized real GDP growth equivalent units.
