Application of Methods for a Morphological Analysis of the Femoral Diaphysis Based on Clinical CT Images to Prehistoric Human Bone: Comparison of Modern Japanese and Jomon Populations from Hegi Cave, Oita, Japan

Table 2

Eigenvectors of a main component analysis with morphological parameters normalized with femoral lengths in modern, Initial/Early Jomon, and Late Jomon Period populations. These vectors were used to calculate the first and second principal component scores ( and ), shown in Figure 6, respectively.

Area of cortical bone	0.571	-0.003
Cross-sectional area	0.552	-0.202
Cortical index	-0.056	0.616
Periosteal border length	0.517	-0.133
Mean cortical bone thickness	0.292	0.544
Maximum cortical bone thickness	0.111	0.517
