各位达人 我是新手现在在做一个单位根检验得到下面结果

Null Hypothesis: FDI has a unit root
Exogenous: Constant, Linear Trend
Lag Length: 0 (Automatic based on SIC, MAXLAG=9)

t-Statistic Prob.*

Augmented Dickey-Fuller test statistic -7.606197 0.0000
Test critical values: 1% level -4.205004
5% level -3.526609
10% level -3.194611

*MacKinnon (1996) one-sided p-values.

想请教我得到的概率为0 代表什么意思啊 Augmented Dickey-Fuller test statistic -7.606197 0.0000 这个概率是越小越好还是越大越好
