“…This is less than, but comparable to, predictions made with the White femur (80.7% overall, range 72-86%: DiBennardo and Taylor, 1979;Taylor and DiBennardo, 1982, and is virtually as great a predictive accuracy as some investigators have found with the inspectional approach to sexing the skull (7770, Stewart, 1948). Moreover, its range of predictive accuracy substantially overlaps those reported in the literature for sexing the skull and postcranial bones, singly and in combination, by discriminant function analysis (Henke, 1977).…”

Stepwise discriminant function analysis for sex assessment was applied to 130 North American Black femora. The measurements included femoral length and three midshaft dimensions likely to be preserved in archaeologically-derived and forensic remains. The method correctly assigned sex for 76.4% of the sample (range 70.8-81.5%). This compares favorably with results achieved with other skeletal parts; it also compares favorably with results using the femur in sexing other racial groups. Among our other conclusions are: (1) a "general size factor" is one of major significance in correct classification and in misclassification of sex, and most misclassified individuals are anomalous for this factor; (2) the inconsistency in the relation between circumference and femoral length, which characterizes the remaining misclassified individuals, suggests that anomalous functional demands of body weight/musculature are at fault, and affect circumference more than length; and (3) discriminant function analysis of the same variables in Whites produced similar results, suggesting that sex overrides race in sex assessment; this was confirmed by cross-validating the predictive accuracy of Black discriminant function coefficients on White data, and vice versa.

“…stable isotope analysis, dating or DNA extraction. Past researchers used measurements of the whole cranium [4,7,12,15], the mandible [6,22] as well as the dentition [25] to determine sex by applying discriminant function analysis and regression equations. These past studies have demonstrated that statistically significant differences exist between male and female skulls.…”

“…However, if faced with an incomplete human skull or a fragment of the cranial base, the correct prediction percentage demonstrated in this study give a statistically useful guide to whether the skull belonged to a male or female when using the correct formulae based on the appropriate population. Furthermore, populations with a similar expression of sexual dimorphism within the foramen magnum region could make use of the same formula or a slightly altered function by artificially changing the sectioning point [11,12]. Further research will concentrate on the use of the occipital condyles alone as well as in conjunction with the foramen magnum for the St. Bride's population in analysing the manifestation of sexual dimorphism.…”

Sex determination from the foramen magnum: discriminant function analysis in an eighteenth and nineteenth century British sample

The successful identification of the deceased is vital to the progress of any forensic investigation. One of the principal biological traits to be established from skeletal remains is the sex of the individual. This becomes more difficult if only parts of a skeleton are found or if the bones are compromised by physical insults such as fire, explosions or violence. The basal region of the occipital bone is covered by a large volume of soft tissue and is therefore in a relatively well-protected anatomical position, and as such, classification of sex using the occipital bone may prove useful in cases of significantly disrupted remains. The aim of this paper is to evaluate manually recorded morphometric variables of the region of the foramen magnum using both discriminant function analysis and linear regression. The skulls utilised in this study were selected from the eighteenth to nineteenth century documented skeletal collection of St. Bride's Church, Fleet Street, London. Adult human skulls n = 158 (male symbol82/female symbol76) were measured to derive statistical functions. The results demonstrated that significant sexual dimorphism is present in the cranial base of the St. Bride's material. The correctly classified crania within this population ranged from 65.8% for univariate functions to 70.3% for multivariate functions within the cranial sample. Males were correctly classified at 70.7% and females at 69.7% using multivariate functions. The linear regression equations predicted sex in the cranial sample correctly for 76% of the males and 70% for the females using different variables; however, overall highest correct prediction percentage was only 68%. Cross-validation brought the percentage down in some cases, but it was concluded that, overall, the expression of sexual dimorphism in the foramen magnum region within the St. Bride's population is significantly demonstrable, and therefore, this area of the skull should be considered useful in the identification of sex.

“…At the same time, they cannot be applied in the cases of Platyrrhines or for Prosimians, for which sexual dimorphism is weak or absent [Schultz, 1969;Martin, 1980], Biometric methods relative to skulls also enable an individual's sex to be determined. These methods are sometimes bivariates [Verheyen, 1957[Verheyen, , 1962 and sometimes mul tivariates [Gilles and Elliot, 1963;Howells, 1964;Defrise-Gussenhoven, 1966, 1967Mahler, 1973;Henke, 1977;Campbell, 1978;Wood, 1979;Calcagno, 1980].…”

Sexual Dimorphism of the Weight of the Skull in African Cercopithecidae (Primates, Catarrhini)

As we had to determine the sex of Cercopithecidae with the help of their skulls, we employed the usual method of measuring the length of their canines. Since we had to consider some doubtful cases, we wondered if we could confirm the diagnosis on the basis of another practical variable. Skull weight seemed to be one such possibility. We weighed 447 skulls from different genera and species of African Cercopithecidae. Whereas the t test confirmed the existence of a sexual dimorphism at this level, discriminant analysis gave a discriminating value to the weights of skulls.
