Explain Multicollinearity in Logistic Regression and how to handle it
Updated May 17, 2026
Short answer
Multicollinearity occurs when independent variables are highly correlated, making coefficient estimation unstable and difficult to interpret.
Deep explanation
Multicollinearity is one of the most important statistical issues in Logistic Regression modeling. It occurs when two or more predictor variables contain highly overlapping information.
For example:
- Annual income and monthly salary
- Total purchase amount and average order value
- Height in inches and height in centimeters
When features are highly correlated, the model struggles to determine which variable is actually responsible for influencing the prediction.
Why Multicollinearity is problematic:
