where (F \sim N(0,I_k)) (with (k = 3) latent factors), (\Lambda) is a loading matrix with elements drawn from (\mathcalU(0.3,0.8)), and (\epsilon \sim N(0,\sigma^2 I_p)) with (\sigma) set to achieve the desired ρ. The true regression coefficients (\beta) were sparse (10 % non‑zero) and drawn from (U(0.5,1.5)).
