WebNov 29, 2024 · Dynamic factor models are parsimonious representations of relationships among time series variables. With the surge in data availability, they have proven to be indispensable in macroeconomic forecasting. This chapter surveys the evolution of these models from their pre-big-data origins to the large-scale models of recent years. http://silviamirandaagrippino.com/code-data

WebDynamic factor model is a special case of a state space equation. In its general form it can be written as X t = Cf t + "t; "t ˘N(0;R) f t = Af t 1 + u t; u t ˘N(0;Q) (1) where X t is a vector of observable data which might contain missing data. It is assumed that observable data is linearly driven by a low-dimensional unobserv- WebRun dynamic factor models (DFM) in R. Adapted from Bok et al. 2024, MATLAB code.
