WebJul 18, 2024 · We provide three marginal screening methods for PLS in this paper, namely, sure independence screening (SIS), profiled independence screening (PIS), and high-dimensional ordinary least-squares projection (HOLP). The promising performance of our methods is illustrated via three near-infrared (NIR) spectral data sets. Webmarginal screening in Algorithm 1. For this experiment we generated Xfrom a standard normal with n= 20 and p= 200. The signal vector is 2 sparse with 0 1; 0 2 = SNR, y= X + , …
WebIn this paper, motivated by the BMD data, we address the large p problem for linear EIV models by proposing two computationally efficient corrected marginal screening methods, namely, corrected penalized marginal screening (PMSc) and corrected sure independence screening (SISc).
