Variable T-statistic P-value Stationary
Trade balance - 1.118557 0.6845 NO
Real income of United States of America. -0.749101 0.8093 NO
Exchange rate -2.098149 0.2474 NO
show the P-value is not significance level at10%
The estimation data of Trade balance t-Statistic is - 1.118557 and probability is 0.6845 Because the computed p-value of 0.6845 is more than significant level at10%.
We cannot reject the null hypothesis( H_0). Therefore, the data of trade balance is nonstationary.
The estimation data of Real income of United States of Americat-Statistic is-0.749101 and probability is 0.8093 Because the computed p-value of 0.8093 is more than significant level at 10%.We cannot reject the null hypothesis( H_0). Therefore, the data ofReal income of United States of America is nonstationary.
The estimation data of exchange rate rate t-Statistic is -2.098149 and probability is 0.2474 Because the computed p-value of -2.098149 is more than significant level at 10%., we cannot reject the null hypothesis( H_0).. Therefore, the data of exchange rate is nonstationary.
