Hierarchical dynamic factor model
Web10 de nov. de 2016 · Real-world data sometime show complex structure that call for the use of special models. When data are organized in more than one level, hierarchical models are the most relevant tool for data analysis. One classic example is when you record student performance from different schools, you might decide to record student-level variables … WebAlthough factor models have been typically applied to two-dimensional data, three-way array data sets are becoming increasingly available. Motivated by the tensor …

To account for the three dominant structural features in the data--functional, time dependent, and multivariate components--we extend hierarchical dynamic linear models for multivariate time series to the functional data setting. We also develop …

Here’s the abstract: This paper presents an approach to dynamic factor modeling in which variations can be idiosyncratic, block-specific, or common across blocks and units. Existing two level factor models do … WebThe Dynamic Factor Models Common factor analysis of multivariate time series data (called P-technique factor analysis) has evolved over the past 60 years. Cattell et al. (1947) fitted a factor model to the covariation of multiple variables measured across time on only one individual. An obvious drawback of P-technique is that it cannot
Web1 de mar. de 2011 · The generalized spatial dynamic factor model (GSDFM, hereafter) is a hierarchical model with a first level measurement equation for conditionally independent univariate observations y t i in the one-parameter natural exponential family, i.e. p ( y t i ∣ η t i, ψ) = exp { ψ [ y t i η t i − b ( η t i)] + c ( y t i, ψ) } where η t i is ...
