In the first test, according to the calculated probability of F-statistic Lymr Table (4-4) and error 05/0 = α, will not be accepted hypothesis H_0 (05/0> 00/0 P =) and using the panel is more appropriate. Also, due to the use of panel data, we use the Hausman test to determine which of the fixed or random effects methods should be used. Hausman test, the hypothesis of random effect H0 is in the opposite hypothesis H1, using fixed effects. In this study, according to the Hausman test probability and error 5.0 = α, will not be accepted hypothesis H_0 (5.0> 4.0P =) and using fixed effects method is more suitable. Results of regression estimates are presented based on fixed methods of entering all independent variables (Table 1).
