本文所用为乌鲁木齐地区出土的200副(男155,女45)成年汉族四肢长骨长度(单位:cm)与重量(单位:g)的测量材料,以骨长为变数,求出推算骨重的回归方程,计男、女各六个。男: 1.肱骨:=6.3211X-72.4411±16.1912(回归系数b=6.3211±0.6231;Y与X的相关系数r=0.5003;X为测得骨长;±16.1912为从X推算Y值的标准估计误差S_(Y·x);回归系数的t值tb=10.1446;下同)。 2.桡骨:=2.7494X-24.2875±5.9495 (b=2.7494±0.2902,=0.4750,
This article uses the measured material of the length (in cm) and weight (in g) of the long bones of the adult Han limbs of 200 (male 155 and female 45) unearthed in the Urumqi region. The bone length is used as a variable to determine the regression of the calculated bone mass. The equation includes six men and six women. Male: 1. Tibia: =6.3211X-72.4411±16.1912 (regression coefficient b=6.3211±0.6231; Y and X correlation coefficient r=0.5003; X is the measured bone length; ±16.1912 is the standard estimate of the Y value derived from X Error S_(Y·x); t value of regression coefficient tb=10.1446; the same below. 2. Tibia: =2.7494X-24.2875±5.9495 (b=2.7494±0.2902,=0.4750,
