Dynamic factor analysis
Web2 Latent Dynamic Factor Analysis of High-dimensional time series We treat the case of two groups of time series observed, repeatedly, Ntimes. Let X1:;t 2R p 1 and X2:;t 2R p 2 be p 1 and p 2 recordings at time tin each of the two groups, for t= 1;:::;T. As in Yu et al. (2009), we assume that a q-dimensional latent factor Zk:;t 2R qdrives each ... WebDynamic factor analysis (DFA) which is a combination of factor and time series analysis, involves autocorrelation matrices calculated from multivariate time series. Dynamic factor models were traditionally used to construct economic indicators, macroeconomic analysis, business cycles and forecasting.

WebDec 13, 2024 · Dynamic factor analysis (DFA) has been used for performing time-series dimension reduction, where latent processes are modelled as random walks. Whereas this may be suitable for some situations, random walks may be too flexible for other cases. WebOct 3, 2016 · A novel formulation which connects the dynamic factor model (DFM) framework with concepts from functional data analysis: a DFM with functional factor loading curves, which results in a model capable of forecasting functional time series and performs very well on forecasting actual yield data.
