7. Consider the following estimated model Aln (GDP, ) = 0.162 + 0.0001t - 0.019(GDP,-1) + 0.261Aln(GDP,-1) + 0.165Aln(GDP;-2) (0.080) (0.001) (0.010) (0.066) (0.066) Conduct the test to analyze whether In (GDP) has a stochastic trend at 10% level of significance. What if we consider 5% level of significance
