Strict factor model
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 … WebMay 12, 2024 · We propose a model-free test for structural changes in factor models. 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 …

Webcovariance matrices are based on the strict factor models, assuming indepen-dent idiosyncratic components. This assumption, however, is restrictive in ... In this paper we use the factor model and assume that XM is sparse, and estimate both XM and X"1 using the thresholding method [Bickel and Levina (2008a), Cai and Liu (201 1)] based on the ... WebSep 21, 2024 · In the model, all factor loadings, thresholds, and residual variances are identical between both time points. The strict invariance model fit the data well (CFI = 0.993, TLI = 0.994, and RMSEA = 0.034). No significant change in CFI, TLI, and RMSEA (ΔCFI = -0.001, ΔTLI = 0, Δ RMSEA = 0.001) indicated that strict invariance of the K6 held over time.

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)).
