Simultaneous component analysis

Webb29 okt. 2015 · ANOVA simultaneous component analysis (ASCA) is an alternative to MANOVA for analysis of metabolomics data from an experimental design. In this paper, we show that ASCA assumes that none of the metabolites are correlated and that they all have the same variance. Because of these assumptions, ASCA may relate the wrong variables … WebbSimultaneous Component Analysis - SCA Description.
