The ACT (STATIS method). (English) Zbl 0825.62009
Summary: ACT (STATIS method) is a data analysis technique which computes Euclidean distances between configurations of the same observations obtained in $$K$$ different circumstances, and thus handles three-way data as a set of $$K$$ matrices. The recent developments of the ACT technique are fully described - concepts and theorems related to Euclidean scaling being discussed in the appendix - and the software manipulation is illustrated on real data.
