Dynamic latent factor model
WebAbstract. Researchers face a tradeoff when applying latent variable models to time-series, cross-sectional data. Static models minimize bias but assume data are temporally independent, resulting in a loss of efficiency. Dynamic models explicitly model temporal data structures, but smooth estimates of the latent trait across time, resulting in ... Webpositive, and the discount factor approaches zero as maturity increases). A third approach is the no-arbitrage dynamic latent-factor model, which is the model of choice in finance. The most common subclass of these models postu-lates flexible linear or affine forms for the latent factors and their loadings along with restrictions
