PMFA: Procrustes Multiple Factor Analysis

Description

Performs Multiple Factor Analysis combined with Procrustean Analysis.

Details

Performs first Multiple Factor Analysis on the tableclothes, then GPA in order to superimpose as well as possible panelist's configuration on the average configuration obtained by MFA (in the case where mean.conf is NULL). If mean.conf is not NULL the configuration used is the one input by the user.

Outputs

Returns the RV coefficient between each individual configuration and the consensus.
If mean.conf is NULL, returns the usual graphs resulting from the afmult function: the graph of the individuals and their partial representations, the graph of the variables (i.e. the coordinates of the products given by each panelist).
If mean.conf is not NULL returns the configuration input by the user.
When matrice.illu is not NULL, returns a graph of illustrative variables.
Returns as many superimposed representations of individual configurations as there are panelists.
