摘要
介绍权的定义、权的性质、协因数传播律,讨论加权回归的本质以及加权回归法在幂函数、指数函数、双曲函数、S型曲线4种拟线性回归模型中的应用。
The paper introduces the definition and its propertiy of weight,propagation law of cofactor,and discusses the nature of weighted regression and how to use the weighted regression in 4 quasi-linear regression models,that is in power function,exponential function,hyperbolic function and S-shape curve regression models.
