最近偶然接触到一种回归算法,叫做前向分布回归(Forward Stagewise Regression),注意这不是那个向前逐步回归(Forward Stepwise Regression),stepwise和stagewise,还是有区别的,网上关于他的介绍非常少,中文社区基本就没怎么看到了,就顺手写一下吧,算法的思想来源于boosting,理解这个也有助于之后对各种树模型的boosting算法的...
Best subsets regression(最佳子集回归) 方法介绍 将自变量所有的组合进行回归,根据组合中的自变脸个数,SSE(Sum of square for errors,误差项的平方和;又称RSS,Residual sum of square)的大小和R_squared(相关系数,correlation coefficient)的大小来选取最合适的估计的回归方程。 例如有3个自变量(A,B,C),那根据组...

I am trying to do a forward variable selection using stepwise AIC in R but I don't think that I am getting the desired results. Specifically, the function should start with no variables and keep adding variables and get their AIC values. However, when I run this I only get an AIC valu...
