Dear All,
I have the impression that studies analyzing one landmark at a time
after a Procrustes superimposition (plus a possible sliding of
semilandmarks) are beginning to pop up here and there in the biological
literature.
I wonder whether there's some revolutionary evidence, which was
published and I missed, that contradicts a most basic principle of
Procrustes shape analysis: never to analyze Procrustes shape variables
one at a time, including especially the case of pairs or triplets of
2D-3D landmark Procrustes shape coordinates. This is nicely summarized
by Paul in J. Anat. (2000) 197, pp. 103–120; exemplified in Fig. 9 of
doi:10.1371/journal.pone.0025630; related to the problem of analyzing
one PW at a time discussed by Jim (Syst. Biol. 47(1):147± 158, 1998);
and most likely known since the early days of Procrustes GMM.
I would be astonished to find that this is not longer true but I am
happy to be surprised.
Many thanks in advance for refs and feedback.
Please, if you reply directly to me, let me know if I can share your
answer.
Cheers
Andrea
