think of ANOVA as an extension of the difference of means test because it’s based‚ in part‚ on a comparison of sample means. At the same time‚ however‚ the procedure involves a comparison of different estimates of population variance—hence the name analysis of variance.

Direct Granger tests will be used to determine the causality between them. Watson and Teelucksingh (2002) said that the co-integration of two variables occurs when the linear combination of the two does not vary. This means that they tend to move together
