Strict factor model
WebThis is also known as the \approximate factor model" in the literature, in contrast to the \strict factor model" where the idiosyncratic components are assumed to be uncorrelated. Note that the model (1) has identi ability issues: given any invertible matrix R 2RK K, simultaneously replacing B with BR and f i with R 1f i does not change the ... WebCarina Coulacoglou, Donald H.

The basic idea is to regress the data on commonly estimated factors by local smoothing and compare the fitted values of time-varying factor loadings with those of time-invariant factor loadings estimated via principal component analysis. By construction, the test is designed …
Webfactor analysis, under the restrictive assumption D = ˙2 " I: 3.1 Asymptotic Principal Components The maximum likelihood method of factor model estimation relies on a strict factor model assumption and a time-series sample which is large relative to the number of assets in the cross-section. Standard principal components WebFactor models such as Fama-French or the other ones that are partially summarized here work on the cross-section of asset returns. How are the factors built, how are sensitivities/coefficients estimated? In this context Fama-MacBeth regressions are usually mentioned. How does this method work intuitively? Could anyone give a step-by-step …

Webbased on observable factors are proposed by Fan et al. (2008) in the case of a strict factor model and Fan et al. (2011) in the case of an approximate factor model. A factor model can serve as the reference point for shrinkage estimation (see Ledoit and Wolf (2012) and Ledoit and Wolf (2004)).
Weba strict factor model. Assumption D is standard in factor analysis and Assump-tion E is standard for regression analysis. These assumptions are similar to those of Stock and Watson (2002a), except that they allow time-varying factor loadings. We only consider time-invariant factor loadings. 2.1.
