: Suggest further optimizations in multivariate analysis.
"XASDS" primarily appears in academic contexts related to and Linear Discriminant Analysis (LDA) , where it represents the product of component scores and loadings.
: Summarize the utility of using component scores/loadings for unit variance.
Here we find it convenient to define Fs as component scores, and AsDs as component loadings. Note, that with this choice the PCs ( papers.ssrn.com Linear discriminant analysis via component scores - SSRN
