Statistical hypothesis testing of factor loading in principal component analysis and its application to metabolite set enrichment analysis
BACKGROUND: Principal component analysis (PCA) has been widely used to visualize high-dimensional metabolomic data in a two- or three-dimensional subspace. In metabolomics, some metabolites (e.g., the top 10 metabolites) have been subjectively selected when using factor loading in PCA, and biologica...
