Differences between stepwisefit and robustfit?
显示 更早的评论
I am trying to do a linear regression between y (100x1) against X (100x5 variable 1,2,3,4,and 5).
What is the best linear regression method I should use: Robustfit or Stepwisefit?
Many thanks.

Hi Leon,
Your choice of model depends on precisely what you are trying to explain. You should have some a priori knowledge that explains
1.Why you are creating a model.
2.What you think that the relationship between the variables should be modeled as.
3.Why you think that the relationship between the variables should be modeled.
