Dynamic factor modeling
WebDynamic factor models have emerged as a widely used tool for obtaining short-term forecasts of economic activity and in⁄ation. These models are usually applied to large data sets that consist of a wide range of di⁄erent series, as suggested by standard considerations from statistical theory.

In econometrics, a dynamic factor (also known as a diffusion index) is a series which measures the co-movement of many time series. It is used in certain macroeconomic models. A diffusion index is intended to indicate • the changes of the fraction of economic data time series which increase or decrease over the selected time interval, WebNov 29, 2024 · Dynamic factor models are parsimonious representations of relationships among time series variables.
