WebDynamic Factor Analysis with the greta package for R - GitHub Pages 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-
