O‘Brien (2007) suggested that a Variance Inflation Factor (VIF) greater than 10 are a sign of

multicollinearity; the higher the value of VIF's, the more severe the problem. Results in table 4.4 show that all the variables had a variance inflation factors (VIF) of less than two and overall VIF of 1.4.These results show that multicollinearity problem was very low.
