By means of the method previously carried-out by performing computerized image analysis we obtained three polinomial equations (7 degree) of best curve fitting for total (fronto-facial), frontal and facial profiles respectively of a standard lateral view of the skull Plesianthropus transvaalensis. The smooth function curves approximating the historical data are perfectly coincident with the scatter diagram for frontal (variance = 0,41) and facial (variance = 0,22) equations, while for the total contour variance raises to 90,8. The finding of the best fit equation is performed by analysis of variance simultaneously to the computation of the coefficients of progressively increasing order equations starting from the second. Then coefficient of determination, standard error of estimate. Standard deviations of coefficients and variance/covariance matrix are calculated with some dimensional parameters as length, eight and projections of profile, relate indexes and arc-chord ratio.
通过之前执行的计算机化图像分析方法，我们分别获得了德兰士瓦南方古猿颅骨标准侧视图的总（额面部）、额部和面部轮廓的三条最佳曲线拟合多项式方程（7次）。近似历史数据的平滑函数曲线与额部方程（方差=0.41）和面部方程（方差=0.22）的散点图完全吻合，而总轮廓的方差则升至90.8。通过方差分析同时计算从二次方程开始的逐步升阶方程的系数，来找到最佳拟合方程。然后计算决定系数、估计标准误差、系数的标准差以及方差/协方差矩阵，同时使用一些尺寸参数，如长度、角度和轮廓投影、相关指数和弦弧比。
