The Nowcast for Real Gross Private Domestic Investment: Fixed Investment: Business: Equipment uses a nowcasting model to synthesize the bridge equation approach relating GDP subcomponents to monthly source data with factor model and Bayesian vector autoregression approaches. For any forecasts occurring on or before the second quarter of 2013, the Gross Private Domestic Investment: Fixed Investment: Business: Equipment was actually Equipment and Software. Currently, Gross Private Domestic Investment: Fixed Investment: Business: Equipment excludes Software.

The Federal Reserve Bank of Atlanta’s GDPNow release complements the quarterly GDP release from the Bureau of Economic Analysis (BEA). The Atlanta Fed recalculates and updates their GDPNow forecasts (called “nowcasts”) throughout the quarter as new data are released, up until the BEA releases its “advance estimate” of GDP for that quarter. The St. Louis Fed constructs a quarterly time series for this dataset, in which both historical and current observations values are combined. In general, the most-current observation is revised multiple times throughout the quarter. The final forecasted value (before the BEA’s release of the advance estimate of GDP) is the static, historical value for that quarter.
