The Generalized Dynamic Factor Model determining the number of factors ∗
This paper develops an information criterion for the choice of the number of common shocks for the approximate dynamic factor model developed by Forni, Hallin, Lippi, and Reichlin (2000). In this framework, the number q of common shocks is associated to the number of diverging eigenvalues of the spectral density matrix of the observations as the number n of time series goes to infinity. The cri...
متن کاملDynamic Factor Analysis for Panel Data: A Generalized Model∗
We develop a generalized dynamic factor model for panel data with the goal of estimating an unobserved performance index. While similar models have been developed in the literature of dynamic factor analysis, our contribution is threefold. First, contrary to simple dynamic factor analysis where multiple attributes of the same cross sectional unit are measured at each time period, our model also...
متن کاملGeneralized spatial dynamic factor models
This paper introduces a new class of spatio-temporal models for measurements belonging to the exponential family of distributions. In this new class, the spatial and temporal components are conditionally independently modeled via a latent factor analysis structure for the (canonical) transformation of the measurements mean function. The factor loadings matrix is responsible for modeling spatial...
متن کاملGeneralized common spatial factor model.
There are often two types of correlations in multivariate spatial data: correlations between variables measured at the same locations, and correlations of each variable across the locations. We hypothesize that these two types of correlations are caused by a common spatially correlated underlying factor. Under this hypothesis, we propose a generalized common spatial factor model. The parameters...
