Problem

How do you deal with multicollinearity in regression?

Explain how you would diagnose it, assess whether it threatens the objective, and select an appropriate remedy. Address the implications for coefficient interpretation, prediction, inference, and model validation. Include a practical workflow and describe when you would retain correlated variables rather than remove them.
