Evaluation of the applicability of regression equations for sorting commingled remains on 3-Dimensional bony elements from CT scans
Abstract This pilot study examines the applicability of osteometric models for addressing commingled remains, which were originally developed for dry specimens, on 3-Dimensional bony elements in relation to a modern cadaveric population. A total of 70 bony elements (humeri, radii, ulnae, femora, tibiae and fibulae) were segmented and virtually reconstructed from cadaveric whole-body CT scans. Linear measurements were taken (using MeshLab v.2016.12) of the 3-Dimensional elements and osteometric models for sorting applied to them (Byrd and Adams, 2003). This study showed that on the selected specimens the quality of the surface of the reconstructed specimens compromised the efficacy of the models, and consequently the reliability of the results.
This paper discusses mainly how to apply the varying coefficient re gression model in the econometrics,fited by the varying coefficient model,we can not only obtain the well fitted value,but also can explore the nonstationa rity in the economical structure explained.
