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...
+1: highly correlated in positive direction-1: highly correlated in negative direction 0: No correlation To avoid or remove multicollinearity in the dataset after one-hot encoding using pd.get_dummies, you can drop one of the categories and hence removing collinearity between the categorical ...
Multicollinearityoccurs when a high degree correlation occurs between two or more independent variables in aregression model. It means that one independent variable can be determined or predicted from another independent variable. Inflation Factor (VIF) is a well-known technique used to detect multicoll...
Using the Variance Inflation Factor (VIF), a VIF > 1 indicates a degree of multicollinearity. A VIF=1 indicates no multicollinearity. The VIF only shows what variables are correlated with each other but the decision to remove variables is in the user's hand.VIF is scale independent so it ...

Furthermore, the correlations among the independent variables are all below 0.6, which indicates a lower concern of multicollinearity. 4.2. Baseline Findings In this section, we examine the effect of customer geographic proximity on the supplier firm’s tax avoidance by estimating the OLS regression...
Regularization methods like LASSO and ridge regression may also be considered algorithms with feature selection baked in, as they actively seek to remove or discount the contribution of features as part of the model building process. Read more in the post:An Introduction to Feature Selection...
(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...
