WebAug 12, 2024 · Here we use the name “factor model” to refer to a general concept where the idiosyncratic components u i are allowed to be weakly correlated. This 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. 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)).
