FCAmet

Computes the ratio Observed/Expected under complete independence
with margins of the multiple contingency table (in frequencies) and
gives <code>chi2</code> statistic of lack of complete independence.

models

 multivariate

A multiway method to decompose a tensor (array) of any order, as a generalisation of SVD also supporting non-identity metrics and penalisations. 2-way SVD with these extensions is also available. The package includes also some other multiway methods: PCAn (Tucker-n) and PARAFAC/CANDECOMP with these extensions.
