多项式回归与局部回归方法

Polynomial regression and partial regressive methods

讨论了多项式回归的存在性、相关程度分析,并且给出了在局部范围内求多项式回归的一种方法.

To random vector X and Y, when we predict another random variable from one,linear regression is a more simple and effective method; When X and Y  are n ot linearly sependent but correspendently dependent, prediction is to solve the regression curve. This article discusses about the existence of polynomial regre ssion and analysis of dependent degree, and offeres a method of polynomial regre ssion partially.
