各位前辈,我在用VAR模型进行分析时,一直纠结于AR根图有根落在单位圆外。eviews中AIC、SC都推荐3阶滞后。我需要进行脉冲响应分析~向各位请教了Roots of Characteristic Polynomial
Endogenous variables: LNCE1 LNY1 LNSTRU LNK
Exogenous variables: C
Lag specification: 1 3
Date: 05/19/11 Time: 22:47

-0.580505 + 0.357809i
0.681919
-0.087152
0.087152
Warning: At least one root outside the unit circle.
VAR does not satisfy the stability condition.
初学,请大家帮忙哈~
