linear relationship between two explanatory variables. Two variables are perfectly collinear if there is an exact linear relationship between the two. For example, X1 and X2 are perfectly collinear if there exist parameters λ0 and λ1 such that, for all observations i, we have X2i = λ0 + λ1X1i. MULTICOLLINEARITY: ...
