However, for the reasons discussed in our implementation of the PCA model, we have decided to use only the first principal component variable. The advantage of the SPCA procedure over PCA is that pollutants not associated or only weakly associated with the adverse health outcomes have a significant chance of being excluded from the chosen model. Hereafter, our implementation of SPCA using the above algorithm will be referred to as the “SPCA model.”
