For this test, the hypotheses are stated as;

The null hypothesis,  infers that a unit root exists, whereas the alternative hypothesis,  infers that there is no root. Once this test has been passed, an appropriate lag length will need to be determined for the VAR model. If any variable does not pass this test and contains a unit root, then it will be invalid and will not be analysed in the further stages.
