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...

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...
