R dynamic factor model with block
WebAbstract This paper uses multi-level factor models to characterize within and between block variations as well as idiosyncratic noise in large dynamic panels. Block-level shocks are … WebIntroduction. Structural equation modeling is a linear model framework that models both simultaneous regression equations with latent variables. Models such as linear regression, multivariate regression, path analysis, confirmatory factor analysis, and structural regression can be thought of as special cases of SEM.

However, I would like to do a full pseudo-out-of-sample forecasting exercise with this package. In other words, I would like to create multiple point forecasts using forecasts generated by this nowcast-function.
WebJul 8, 2011 · Dynamic factor models postulate that a small number of unobserved “factors” can be used to explain a substantial portion of the variation and dynamics in a larger number of observed variables. A “large” model typically incorporates hundreds of observed variables, and estimating of the dynamic factors can act as a dimension-reduction ...
