%description
Implements bridge models for nowcasting and forecasting macroeconomic
variables by linking high-frequency indicator variables (e.g., monthly
data) to low-frequency target variables (e.g., quarterly GDP). Simplifies
forecasting and aggregating indicator variables to match the target
frequency, enabling timely predictions ahead of official data releases.
For more on bridge models, see Baffigi, A., Golinelli, R., & Parigi, G.
