摘要
本文讨论回归系数相同,回归常数不同的回归分析模型。因为不知道哪些样本有相同的回归常数,所以需要先对样本进行聚类分析,找出有相同回归常数的样本,然后进行回归分析。这种模型具有原来回归模型求解的简单性,却得到了更好的结果。
This paper presents regression model with same regression coefficient and different regression constants.As the exact samples with same regression constant are unknow may identify the samples by clustering analysis method,then have the results of regression analysis and the cluster- ing regression model follows.This model is as simple as the common one,but has better results.
