La connessione e la correlazione tra due matrici dei dati componenti una matrice a tre indici

M. Vichi
In this work, starting from the statistical knowledge about connection and correlation between couples of variables, the author carries out a systematic study and a critical examination on these two relations among couples of data matrices belonging to a three-way data matrix. Analogously to linear measures among variables, the measures of correlation between two matrices have to indicate the "direction" of dependence of the whole variables set of a data matrix with that of the...
