Odhad věku dožití dospělého jedince podle kostry: Nové přístupy hodnocení indikátorů senescence

Kotěrová, Anežka

Age-at-death estimation of adults is still a very difficult part of estimation of individual's biological profile. Current age estimation methods can estimate age accurately and reliably only as very broad age ranges. The fact that these approaches are mostly based on only one skeletal indicator, whose age changes are assessed visually, or are based on an inappropriate statistical approach, does not contribute to the improvement of this situation. The dissertation project is based on these shortcomings and it aims to contribute to a better understanding of the issue and to integrate and test new technologies and computational approaches in research. Given the methodological nature of this dissertation, the whole research was divided into three separate parts, which corresponds to the establishment of three main objectives. The first objective was to apply different sophisticated mathematical techniques in a multi-population database of visually evaluated data (n=941) of two articulation surfaces of os coxae to achieve a more accurate estimate of age. However, the resulting RMSE, which ranged between 12 to 14 years, do not indicate an accurate estimate. Furthermore, we focused on the evaluation of outputs from various scanning devices and we tested the influence of possible differences in captured...
