During data preparation, we watch out for multicollinearity, which occurs when independent variables in a regression model are correlated, meaning they are not independent of each other.This is not a good sign for the model, as multicollinearity often leads to distorting the estimation of regression...
After mean centering our predictors, we just multiply them for adding interaction predictors to our data. Mean centering before doing this has 2 benefits:it tends to diminish multicollinearity, especially between the interaction effect and its constituent main effects; it may render our b-coeffici...
Gradient boosting algorithms are based on decision trees and are therefore robust to multicollinearity in predictors. In addition, they natively support missing values, without the need for deletion or imputation. The LightGBM model was trained with 50 estimators and a random subsampling of all ...
Identification and prevention of multicollinearity in MGWR In an MGWR model, multicollinearity can occur in various situations: One of the explanatory variables is spatially clustered. To prevent this, map each explanatory variable and identify the variables that have very few possible...

In January 2021, the stock price of NASDAQ-listed GameStop Corporation surged more than twenty-fold for no discernible economic reason. Many observers attr
(Online Appendix TableH.1), I include other metrics reported in factsheets (e.g., Sharpe ratio, tracking error, information ratio) and find that doing so does not alter the inferences. I do not include these metrics in my baseline analysis due to their modest multicollinearity with CAPM ...
(LightGBM,11) was used as the primary analytical method for the between-person analysis. Gradient boosting algorithms are based on decision trees and are therefore robust to multicollinearity in predictors. In addition, they natively support missing values, without the need for deletion or imputation...

To detect multicollinearity in a dataset, use the following methods: Correlation Matrix: Check for high absolute correlation values (close to 1 or -1). Variance Inflation Factor (VIF): VIF values above 10 indicate high multicollinearity. Eigenvalues and Condition Number: High condition numbers (abov...
