我用成本函数分析8年面板数据,结果如下:
the final mle estimates are :
coefficient standard-error t-ratio
beta 0 0.12988202E+02 0.18003246E+01 0.72143671E+01
beta 1 0.25472796E+00 0.87817717E-01 0.29006443E+01
beta 2 -0.13965871E+00 0.16559294E+00 -0.84338566E+00
sigma-squared 0.22136410E+02 0.10514822E+01 0.21052577E+02
gamma 0.58748620E+00 0.25571786E-01 0.22974000E+02
mu 0.72124435E+01 0.21847467E+01 0.33012721E+01
eta -0.30411702E-01 0.87175728E-02 -0.34885515E+01
log likelihood function = -0.10997135E+04
LR test of the one-sided error = 0.91367021E+02
with number of restrictions = 3
其中sigma-squared、mu、eta分别代表什么?变差率是看哪个数?
天哪,我是非统计出生,看这些结果很迷茫,还望高人能帮忙解读下,在这里谢谢了!
