Overview of STATIS. Six data tables are considered for this analysis: two tomato varieties, peach, pepper, and two strawberry organs; here, a data table is composed of 16 metabolites (variables) and developmental stages (observations). The scalar product captures the covariances of each metabolite pair (A). Based on data table similarity, a new matrix of data table similarity can be derived (B). Successively, a PCA (C) of this compromise yields weights for the combination of all six data tables (D) that allow the data tables to be combined in a common representation, the compromise (E).
