Exploration and variation of vertebrae

Data resembling possible universal and non-specific standards for assessing vertebrae. The dimensions of the vertebrae in the various types were compared to see if specific vertebrae had to be identified before further analysis Additionally, size variation among sequential vertebrae within and among the different subtypes (i.e., cervical, thoracic, and lumbar vertebrae) were also considered to determine possible single vertebral or combined vertebral standards for population affinity and sex estimation. Using the information from the variation exploration component, classification models were created to gauge the predictive accuracy of vertebral measurements when estimating population affinity and sex. The classification component focused on the quantifiable differences in the vertebrae in order to develop standards that can be used to estimate population affinity and sex in South Africa. All in all this component assessed whether universal, non-specific standards can be established or if a specific vertebra needs to be identified first before classification can occur.本数据集涵盖用于探索椎骨（vertebrae）评估通用非特异性标准的相关数据。研究首先对不同类型椎骨的尺寸进行比对分析，以明确是否需先识别特定椎骨方可开展后续分析。此外，本研究还考量了不同亚型（即颈椎、胸椎、腰椎）内部及亚型间连续椎骨的尺寸变异情况，以此确定可用于人群亲缘（population affinity）推断与性别推断（sex estimation）的单椎骨或组合椎骨标准。基于变异探索环节所获取的信息，研究构建了分类模型（classification models），用以评估椎骨测量值在推断人群亲缘与性别时的预测准确率（predictive accuracy）。分类环节聚焦于椎骨的可量化差异，旨在制定适用于南非人群的亲缘推断与性别鉴定标准。综上，本研究环节旨在评估是否可建立通用非特异性标准，或是需先识别特定椎骨后方可开展分类工作。
