CONCOR method

Analyses of the links between subsets of variables measured on one set of cases.

The SVD notion extended to several matrices corresponds to the function svdcp (for a column partitioned matrix), itself extended by svdbip or svdbip2, and by svdbips. (for a bi-partitioned matrix).

"Procrustes analyses", simultaneous regressions, or proximity analyses of a set of variables with another sets, correspond to the functions concor, concoreg and concorcano
These 3 analyses are extended for analyzing the links of several sets with several another sets, with the functions concorgm, concorgmreg and concorgmcano.
The 3 other functions (concors, concorsreg, concorscano) are given for calculating a set of simultaneous solutions instead of successive solutions.
The CONCOR method is written from 1997 to today by several authors.
