Multicollinearity arises when two or more regressors are correlated in multiple linear regression model (MLRM) and in most cases, one regressor variable can be predicted from another. Multicollinearity majorly results in inefficient regression model estimates and poor performance of the regression model. However, multicollinearity problem can easil...
