A Statistical Investigation Of Nonmetric Vertebral Traits With A Skeletal Population Sample From The Dakhleh Oasis, Egypt, Tiffany A. Sarfo
A Statistical Investigation Of Nonmetric Vertebral Traits With A Skeletal Population Sample From The Dakhleh Oasis, Egypt, Tiffany A. Sarfo
Electronic Thesis and Dissertation Repository
This paleogenetic study utilizes 17 nonmetric epigenetic vertebral traits to determine their suitability for studying past genetic relationships. The samples utilized were from Egypt’s Dakhleh Oasis. Though infracranial nonmetric traits have a limited role in the study of past population genetics, this study has shown their value for elucidating past genetic patterns for intragroup analysis. The key to their utilization is to test the epigenetic factors (e.g., age, sex, symmetry and intertrait correlations) which were done using a number of statistical tests including Phi coefficient, G-test and the Odds ratio. This study utilized a novel set of spatial statistics to …
Statistical Analysis Of Nonmetric Cranial Trait Interactions In A Skeletal Population Sample From The Dakhleh Oasis, Egypt, Lisa C. Brown
Statistical Analysis Of Nonmetric Cranial Trait Interactions In A Skeletal Population Sample From The Dakhleh Oasis, Egypt, Lisa C. Brown
Electronic Thesis and Dissertation Repository
Skeletal nonmetric traits have been used since the 1960s in genetic distance analyses, largely ignoring the potential for intertrait correlation. Using a skeletal population sample from the Dakhleh Oasis, Egypt, this thesis tests the null hypothesis that intertrait correlation is not occurring in the population at a significant level. Additionally, this thesis tests whether the odds ratio is a suitable statistical test for intertrait correlation. Using the phi coefficient and odds ratio, pairwise comparisons between 39 cranial nonmetric traits were calculated. The results of the statistical analysis show that intertrait correlation is occurring in the Dakhleh Oasis at a significant …
