Abstract
We present a Factor Analysis technique useful for the study of data tables which contain a partition of the individuals set, defined in a natural way. Such a technique allows to exhibit the relations that exist between individuals belonging to the same class, discriminating them from the members of other classes using the relative weights assigned to these classes. By an appropriate selection of the class weights, the new methodology obtains local variables of the Partial Analysis, with the advantage of a representation of the individuals, as active elements, of the local axes.References
