5. ''Superimposed representations of individuals'' « seen » by each group. An individual considered from the point of view of a single group is called ''partial individual'' (in parallel, an individual considered from the point of view of all variables is said ''mean individual'' because it lies at the center of gravity of its partial points). Partial cloud <math>N_i^j</math> gathers the <math>I</math> individuals from the perspective of the single group <math>j</ math> (ie <math>{i^j, j = 1, J}</math>): that is the cloud analysed in the separate factorial analysis (PCA or MCA) of the group <math>j</math>. The superimposed representation of the <math> N_i^j</math> provided by the MFA is similar in its purpose to that provided by the [[Procrustes analysis]].
