descriptive analysis to make an inference, the data does support hypothesis that increased expenditures generated more WC cases over 42-month period. Hypothesis can be rejected for PI cases. However, month 24, 830 dollars was spent and 45 cases were generated. Week 15, 13605 was expended, yet they only generated 37 new cases. This shows there isn’t a causal relationship between the amount of money spent and the total number of cases generated. Post 2 Doing the Descriptive Statistical Analysis for

demographical structure of population on saving per capita I could predict the future saving and investment in countries using the obtained results of influence. The model. To define, what could also has the impact on savings and what I could add to my regression mode, I analyzed some economical articles and papers. In that case, I started by reading the research work of F. Modigliani, famous Italian economist and Nobel-awarded, about the conception of the life-cycle model. Working out this conception,

the analysis we have developed a panel data set consisting of FDI and inflation data of all three countries from 1988 to 2014. One important aspect of this analysis is test the notion that unobservable factors that might simultaneously affect the left hand side and right hand side of the regression are time-invariant. To test this, we need to use Fixed Effects (F-E) model and Random Effects (R-E) model. We used STATA for necessary analysis. Results are presented below: Simple OLS regression (see
