Chicago Fed Nat’l Activity Index: Aug 2015 Preview

The three-month average of the Chicago Fed National Activity Index (CFNAI) is expected to rise modestly in the August update that’s scheduled for tomorrow (Sep. 24), based on The Capital Spectator’s average point forecast for several econometric estimates. The projection for +0.08 is slightly above July’s zero reading, which reflects economic growth that matches the historical trend. Only negative values below -0.70 indicate an “increasing likelihood” that a recession has started, according to guidelines from the Chicago Fed. Using today’s estimate for August as a guide, CFNAI’s three-month average is expected to reflect an expansion that’s slightly above the historical trend rate for growth and therefore well above the tipping point that marks the start of a new recession.

Here’s a closer look at the numbers, followed by brief definitions of the methodologies behind The Capital Spectator’s projections that are used to calculate the average forecast:

VAR-4A: A vector autoregression model that analyzes four economic time series to project the Chicago Fed National Activity Index: the Capital Spectator’s Economic Trend & Momentum Indexes, the Philadelphia Fed US Leading Indicator, and the Philadelphia Fed US Coincident Economic Activity Indicator. VAR analyzes the interdependent relationships of these series with CFNAI through history. The forecasts are run in R with the “vars” package.

VAR-4B: A vector autoregression model that analyzes four economic time series to project the Chicago Fed National Activity Index: US private payrolls, real personal income less current transfer receipts, real personal consumption expenditures, and industrial production. VAR analyzes the interdependent relationships of these series with CFNAI through history. The forecasts are run in R with the “vars” package.

ARIMA: An autoregressive integrated moving average model that analyzes the historical record of the Chicago Fed National Activity Index in R via the “forecast” package.

ES: An exponential smoothing model that analyzes the historical record of the Chicago Fed National Activity Index in R via the “forecast” package.
