Webmodels in which the factor loadings are time-varying. We consider two empirical applications of our testing procedure. We use the dataset of Mc-Cracken and Ng (2015) for the US economy, and we apply our testing procedure for di erent choices for the number of factors. We nd evidence of time-varying factor loadings in over half of series, 2 WebFredj Jawadi, Wael Louhichi, Abdoulkarim Idi Cheffou, Hachmi Ben Ameur Modeling time-varying beta in a sustainable stock market with a three-regime threshold GARCH model, Annals of Operations Research 281, no.1-2 1-2 (Feb 2024): 275–295.
