Generalized procrustes analysis

Gower, J. C.·1975·Psychometrika

Abstract

Suppose P i ( i ) ( i = 1, 2, ..., m, j = 1, 2, ..., n ) give the locations of mn points in p -dimensional space. Collectively these may be regarded as m configurations, or scalings, each of n points in p -dimensions. The problem is investigated of translating, rotating, reflecting and scaling the m configurations to minimize the goodness-of-fit criterion Σ i=1 m Σ i=1 n Δ 2 ( P j ( i ) G i ), where G i is the centroid of the m points P i ( i ) ( i = 1, 2, ..., m ). The rotated positions of each configuration may be regarded as individual analyses with the centroid configuration representing a consensus, and this relationship with individual scaling analysis is discussed. A computational technique is given, the results of which can be summarized in analysis of variance form. The special case m = 2 corresponds to Classical Procrustes analysis but the choice of criterion that fits each configuration to the common centroid configuration avoids difficulties that arise when one set is fitted to the other, regarded as fixed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
