Popis: A general strategy for setting up supervised methods of multiblock data analysis is outlined. This yields a unified framework where some already known methods are retreived and novel extensions are introduced. All the methods of analysis are based on the determination of latent variables associated with the various blocks of variables. They are derived from clear optimization criterion whose aim is to maximize either the sum of the covariances or the sum of squared covariances between the latent variable associated with the response variables and the block latent variables associated with the various explanatory datasets. New indices are proposed to help better interpreting the outcomes of the analyses. The methods are illustrated and compared based on simulated and real datasets.
