Analyzing the experimental datum by regression, it draws the different influences of the modification of the weights of two kinds of control points on length of NURBS curve.
将实验数据回归分析，在此基础上得出两类控制顶点权因子的改变对NURBS曲线长度不同的影响结果。

We study restriction of Nonlinear Regression Diagnostic Models with case-weights and meanshifte simultanously, and some new diagnostic statistics are derved.
研究了带有约束的均值漂移和方差加权的混合非线性回归模型．得到了相应的一阶和二阶诊断统计量。

Besides, the author measured the weights of different variables 'effects using regression analysis.
