Estimation of pubic age among Chinese Han people by means of multiple stepwise progressive analysis
Abstract:
This paper sets up an equation for estimating male and female ages separately by means of a computer with mathematical model of multiple stepwise progressive regression on data of 454 pairs of pubes of Chinese Han people in Northeast China. The equation upgrades a standardization of pubic age estimation to quantification. The correlation coefficient of the equation is 0.9906-0.9912; S.D. is 1.56-1.97; variance analysis F greater than 001 and p less than 0.01. By a blindfold test of 43 pairs of pubic bones with birthdate, the rate of concordance is 76-82% for +/- S.D. and 92-96% for +/- 2S.D.
