哈,终于弄明白了,问题出在单位根检验那里了,谢谢大家。
你好,我也有同样的疑问。所有序列都是一阶单整的,怎么还有一个点在圆外呢?Roots of Characteristic Polynomial
Endogenous variables: LNERER LNGDP LNM
Exogenous variables: C
Lag specification: 1 2
Date: 09/05/12 Time: 14:24
Root Modulus
1.026901 1.026901
0.732946 - 0.047852i 0.734507
0.732946 + 0.047852i 0.734507
0.429301 - 0.274656i 0.509643
0.429301 + 0.274656i 0.509643
-0.212693 0.212693
Warning: At least one root outside the unit circle.
VAR does not satisfy the stability condition.
希望高手指点呀!
