WebMay 9, 2024 · To answer the original question posed first: the finding of collinearity in the model is not necessarily a red flag as it is sometimes treated. It may not even be an orange alert either. It is conveying important information about the data-set which needs to be looked at before further interpretation is made. WebSep 29, 2024 · The Farrar-Glauber test (F-G test) for multicollinearity is the best way to deal with the problem of multicollinearity. The F-G test is, in fact, a set of three tests for testing multicollinearity. Firstly, a Chi-square test for the detection of the existence and severity of multicollinearity is a function with several explanatory variables.
