instrustion in general (detail instructions uploaded in additional materials)

what needs to be changed and done: amend literature review, better methodology with better explanations, more independent variables that may also affect tobacco sales should be included, and the other parts of dissertation.

econometric: need to use SPSS to do unit root test, co-integration test and regression (please feel free to use more tests or other tests if appropriate)

(other non-quantitative policies also need to be considered, probably after the regression analysis, to explain the change in tobacco sales)
