此论坛上有位大师已指了一部分实务操作(你可以在论坛上输入关键字即可搜索到。),只是我个人认为这其中的矩 ...
Model: Ae = Bu where E[uu']=I
Restriction Type: short-run pattern matrix
A =
1 0 0
C(1) 1 0.011
C(2) C(3) 1
B =
1 0 0
0 1 0
0 0 1
WARNING: B matrix is fixed (structural innovation variances not estimated)!!!
Coefficient Std. Error z-Statistic Prob.
C(1) 0.100000 0.078811 1.268858 0.2045
C(2) 0.100000 0.079195 1.262699 0.2067
C(3) 0.100000 0.078715 1.270409 0.2039
Log likelihood -44413335
LR test for over-identification:
Chi-square(3) 88821793 Probability 0.0000
Estimated A matrix:
1.000000 0.000000 0.000000
0.100000 1.000000 0.011000
0.100000 0.100000 1.000000
Estimated B matrix:
1.000000 0.000000 0.000000
0.000000 1.000000 0.000000
0.000000 0.000000 1.000000
能帮我看下吗?为什么矩阵估计值都是0.1啊 论文就卡在这里了, 谢谢~!!
