  • Q2. What is multicollinearity? How to tackle this condition?
  • Ans. 

    Multicollinearity is a phenomenon in which two or more predictor variables in a regression model are highly correlated.

    • Multicollinearity can lead to unstable estimates of the coefficients and make it difficult to determine the effect of each predictor variable on the outcome.

    • One way to tackle multicollinearity is to identify the highly correlated variables and consider removing one of them from the model.
