Procrustes analysis (PA)

Procrustes analysis (PA) is about transforming some configuration of points in the plane/space to fit into a given specific pattern of points. PA is named after the character Procrustes from the Greek mythology, a robber dwelling somewhere in Attica (and son of Poseidon). Procrustes had an iron bed (or, even two beds) on which he forced his victims to lie. If a victim was shorter than the bed, he stretched him to fit. Alternatively, if the victim was longer than the bed, he cut off his legs to make the body fit the bed’s length.
