Multicollinearity occurs in a multiple regression model when two or more explanatory variables are highly correlated, making it difficult to isolate their individual effects on the dependent variable. It inflates the standard errors of the estimated coefficients, leading to unreliable t-tests and wide confidence intervals. To address multicollinearity, several remedial measures can be adopted. One approach is to examine the correlation matrix of the explanatory variables and remove one of the highly correlated variables, especially if it is theoretically less important. Another
