Comparing generalized procrustes analysis and statis [PDF]
Food Quality and Preference, 2000 We consider a model for sensory profiling data including translation, rotation and scaling. We compare two methods to calculate an overall consensus from several data matrices: GPA and STATIS. These methods are briefly illustrated and explained under our model. A series of simulations to compare their performance has been carried out.

Body shape analysis of Bosnian mountain horses using Procrustes statistics [PDF]
Italian Journal of Animal Science, 2009 Procrustes analysis was performed on 4 samples of horse populations (11 Bosniak horses from a private farm in Nevesinje, 2 Bosniak horses from a former state farm in Han Piesak, 12 Bosniak horses from the former state stud farm Borike and 18 purebred ...

Fréchet means and Procrustes analysis in Wasserstein space [PDF]
Bernoulli, 2019 We consider two statistical problems at the intersection of functional and non-Euclidean data analysis: the determination of a Fréchet mean in the Wasserstein space of multivariate distributions; and the optimal registration of deformed random measures and point processes.

Highly Efficient Knowledge Graph Embedding Learning with Orthogonal Procrustes Analysis [PDF]
North American Chapter of the Association for Computational Linguistics, 2021 Knowledge Graph Embeddings (KGEs) have been intensively explored in recent years due to their promise for a wide range of applications. However, existing studies focus on improving the final model performance without acknowledging the computational cost ...

Sexual Monomorphism and Size-Related Shape Change in the Beak of the Greater Flamingo (Phoenicopterus roseus). [PDF]
Vet Med SciBackground The avian beak is a functionally important structure shaped by ecological demands. In highly specialized filter‐feeders such as flamingos, subtle variation in beak size and shape may influence feeding performance.

Perturbation Theory for Generalized Procrustes Analysis
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1985 SUMMARY Perturbation theory for Procrustes statistics is developed when both configurations are subject to independent normal errors. The total sum of squares is shown to partition into sums of squares for translation, rotation/reflection and scaling, plus a residual. These results are extended to generalized Procrustes analysis.

PACo: A Novel Procrustes Application to Cophylogenetic Analysis [PDF]
PLoS ONE, 2013 We present Procrustean Approach to Cophylogeny (PACo), a novel statistical tool to test for congruence between phylogenetic trees, or between phylogenetic distance matrices of associated taxa. Unlike previous tests, PACo evaluates the dependence of one phylogeny upon the other.

Procrustes Analysis with Deformations: A Closed-Form Solution by Eigenvalue Decomposition [PDF]
International Journal of Computer Vision, 2022 Generalized Procrustes Analysis (GPA) is the problem of bringing multiple shapes into a common reference by estimating transformations. GPA has been extensively studied for the Euclidean and affine transformations.
