it also grows in size. It leads to a multicollinearity problem in the OLS regression analysis. If the independent variables in a regression model show a perfectly predictable linear relationship, it is known as perfect multicollinearity.
In multiple regression (Chapter @ref(linear-regression)), two or more predictor variables might be correlated with each other. This situation is referred as collinearity. There is an extreme situation, called multicollinearity, where collinearity exists between three or more variables even i...

where 𝑅2𝑗Rj2 is the multiple 𝑅2R2 for the regression of a feature on the other covariates. The VIF is a measure of how strongly a predictor variable is related to other predictors in a regression model. A higher VIF indicates lower information entropy, suggesting stronger multicollinear...
Moreover, the motif combinations found can be analyzed through traditional statistical approaches avoiding statistical corrections for multiple tests.
