Augmented Dickey-Fuller unit root test on d(ele).

Augmented Dickey-Fuller test statistic	-statistic	Prob.
	−3.726070	0.0248
Test critical values:
1% level	−4.046925
5% level	−3.452764
10% level	−3.151911

Prob. is the value; the smaller the value, the larger the significance. indicates to reject the original hypothesis under the confidence level of 95%.
