R语言建立回归分析,并利用VIF查看共线性问题的例子 使用R对内置longley数据集进行回归分析,如果以GNP.deflator作为因变量y,问这个数据集是否存在多重共线性问题?应该选择哪些变量参与回归? 答: ## 查看longley的数据结构str(longley) ## 'data.frame': 16 obs. of 7 variables: ## $ GNP.deflator: num 83 88...
...[j], res[i, j]]) vif_value = sorted(vif_value, key=lambda x: x[2]) if k is not None:...if vif_value[-i][1] not in new_c: new_c.append(vif_value[-i][1])...答案之一就是共线性检验啊,判断feature之间的相关性,剔除相关性较高的feature,在R语言里面有个VIF函数可以直接...
