Popis:	It is suggested that factor matrices be scaled for presentation—not just computation—so that the test vectors in the common factor space all become and remain of unit-length, the termini of which all lie on the surface of a unit hypersphere. This implies that factor matrices representing uncorrelated (“orthogonal”) factors are row-normalized. [Factor matrices representing correlated (“oblique”) factors would also have test vectors of unit-length, but the row vectors in such a matrix would not be normalized because of the nonorthogonality of such vectors.]
