摘要
运用主成分分析法提取了十二种足骨发育等级的主分量,接着进行主分量回归,然后再进行分年龄段回归,可得用于年龄鉴定的骨龄系数表。
Using the method of principal component analysis, the principal component is extracted from twelve growth grade of foot bones, and the regression of the principal component is followed, then the regression of partitoning age group is conducted,finally table of the bone-age coefficient for determination of person' s age is obtained,
