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.

The relationship between form and function of the carnivore mandible

The Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Procrustes analysis of a shape of pediatric supracondylar humerus fractures

Scientific Reports
Shape of supracondylar fracture of the humeral of pediatric patients is analysed with Procrustes method. XR-images of fractures are considered both in anterio-posterior (AP) view and in a lateral (L) view.

Spatiotemporal Dynamics in Bird Species Assembly in the Coastal Wetlands of Sicily (Italy): A Multilevel Analytical Approach to Promote More Satisfactory Conservation Planning

Land
The Sicilian wetlands (Italy) are seriously threatened by human activities and ongoing climate change. The loss of these wetlands as migratory stepping stones could severely hamper the migratory flow of many bird species along the central Mediterranean ...

Bayesian matching of unlabelled point sets using Procrustes and configuration models [PDF]

, 2010
The problem of matching unlabelled point sets using Bayesian inference is considered. Two recently proposed models for the likelihood are compared, based on the Procrustes size-and-shape and the full configuration.

Distal femoral morphology as a risk factor for osteoarthritis

The Anatomical Record, EarlyView.
Abstract Osteoarthritis (OA) is a leading cause of disability affecting millions of adults in the United States, commonly resulting in the need for total knee arthroplasty (TKA) to restore mobility and quality of life. This study investigates potential differences in baseline distal femoral shape between individuals who received TKA due to OA and a ...

Construction of a time-scaled topology map of indoor WiFi access points for human mobility analysis from WiFi log

Geo-spatial Information Science
This study proposes a heuristic approach for constructing time-scaled topology maps of indoor WiFi networks using only WiFi log data, without relying on access point (AP) coordinates or signal strength measurements.

Geometric morphometric comparison of three populations of Mesopotamian minnow (Barilius mesopotamicus Berg, 1932) in Jarrahi River basin [PDF]

بوم‌شناسی آبزیان, 2019
The present study compared the geometric morphometrics of Barilius mesopotamicus populations, one of the native cyprinids in Jarrahi River basin. For this purpose, 166 fish specimens from three populations of Aalaa, Zardmashin, and main Jarrahi rivers ...

Integrating mandibular evidence to assess morphological variation of the Australopithecus afarensis maxilla

The Anatomical Record, EarlyView.
Abstract Geometric morphometric analyses are used to explore variation of maxillary dental arcades of Australopithecus afarensis, expanding on the work of Hanegraef and Spoor, 2025 (Morphological variation of the Australopithecus afarensis maxilla.
