Bridge equations
Simple regressions that bridge from monthly indicators to a quarterly target like GDP, refreshed as each indicator lands.
Best for: A transparent first-pass nowcast of a quarterly series from a small set of monthly indicators.

Empirical · Model class
High-frequency reads of the current quarter from incoming releases -- designed to update as new data lands rather than wait for the official print.
What this class is for
Use this class when you need a current-quarter read that updates with each new monthly or weekly indicator instead of waiting for the GDP print.

Simple regressions that bridge from monthly indicators to a quarterly target like GDP, refreshed as each indicator lands.
Best for: A transparent first-pass nowcast of a quarterly series from a small set of monthly indicators.
Extracts a small number of latent factors from many macro indicators and lets those factors drive a current-quarter read.
Best for: Nowcasting from a wide indicator panel where many series carry overlapping signal about the same underlying macro state.
Mixed-data sampling regressions that handle indicators arriving at different frequencies inside a single forecasting equation.
Best for: Combining monthly, weekly, or daily indicators into one forecasting equation for a lower-frequency macro target.
