Abstract
One of the most useful techniques to analyse latent structures is exploratory Factor Analysis. When se,wal data matrices, arising from different occasions and/ or groups. are obtained, the comparison and integration of the resulting latent spaces is an important task. In this paper we propase a factor model far severa! groups th at includes shared common (actors far ali the groups and speci(ic (actors far each group. Shared common factors are obtained from the common directions of the separated latent subspaces and specific factors from the residuals after projecting the group onto the common subspace.
