Farrar glauber test

Multicollinearity was assessed using variance inflation factor (vif) , which measures the inflation in the variances of the parameter estimates due to multicollinearity potentially caused by the correlated predictors in each scenario for correlation matrix the average estimates of regression coefficient, standard errors, t-test statistics, p. Farrar-glauber test is one of the statistical test used to detect multicollinearity this comprises of three further tests the first, chi-square test, examines whether multicollinearity is present in the system.
