为了充分利用现场遗留足迹推断作案人的身高特征,我们对提取的250名不同年龄、不同性别人的500枚赤足足迹的捺印样本进行分析测量,并选取其中的5个特征作为研究指标,分别利用一元线性回归和多元线性回归的方法对身高进行多因素分析,并且建立了相应的一元线性回归方程和多元线性回归方程,同时就各因素对身高的影响进行了分析比较,为足迹检验工作提供参考。
In order to make full use of the left footprints of the scene to infer the height characteristics of the perpetrators, we analyzed and measured the imprinted samples of 500 barefooted footprints from 250 different age and sexes, and selected five of them as the research indicators, Univariate linear regression and multivariate linear regression analysis of the height of the multi-factor analysis, and the establishment of the corresponding linear regression equation and multiple linear regression equation, while the impact of various factors on the height were analyzed and compared to provide reference for the footprinting test .
