[Osteometric method of determination of ordinal localization of the ribs using discriminant analysis].
III-XI right ribs from 86 skeletons of the Caucasoid, stored in the Chair of Anthropology of Moscow State University, were examined. The ribs were measured by A. I. Turovtsev's program (1972) including 13 signs. The results have been analyzed with statistic program SPSS. Diagnostic models, based on incremental discriminant analysis, were calculated for expert practice. It is recommended to perform the expertise in 2 stages. On 1st stage group belonging of the rib has to be established. 1st group include III-V ribs, 2nd group--VI-VIII and 3rd--IX-XI ones. To determine ordinal localization of I, II and XII ribs is not difficult in view of uniqueness of its anatomic structure. Precision of classification of group localization of a rib is 99.6%. On 2nd stage individual number of the rib has to be determined. Precision of classification in case of belongings of the rib to 1st or 3rd groups is 80.2% and 85.7% respectively, to 2nd group it is lower (41.7-69%).
