Generalized procrustes analysis aligns different subjects’ attribute ratings into common dimensions.

Evidence

A data analysis procedure known as generalized procrustes analysis (Gower and Hand, 1995) is then used to project the results to a common set of dimensions representing the sensory attributes. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 941

• QUESTION: How exactly does generalized procrustes analysis rotate/scale individual subject spaces to align them? Worth chasing the Gower and Hand reference.
