WebThe permutation importance plot shows that permuting a feature drops the accuracy by at most 0.012, which would suggest that none of the features are important. This is in contradiction with the high test accuracy computed above: some feature must be important. The permutation importance is calculated on the training set to show how much the ... Web29 sept. 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.
WebWhat is Multicollinearity?

Web1 mar. 2024 · If we conclude that multicollinearity poses a problem for our regression model, we can attempt a handful of basic fixes. Removing variables. A straightforward method of correcting multicollinearity is removing one or more variables showing a high correlation.
