您好,我想问下,你最后显著性是怎么看的,怎么看有没有进行SFA分析的必要?下面是我用Frontier运行出来的,看不明白。
the final mle estimates are :
coefficient standard-error t-ratio
beta 0 -0.10692908E-02 0.13794677E+00 -0.77514743E-02
beta 1 -0.77080639E-05 0.95051548E-03 -0.81093512E-02
beta 2 0.11823871E-03 0.13944780E-01 0.84790655E-02
sigma-squared 0.45332487E+00 0.12752648E+02 0.35547508E-01
gamma 0.99999716E+00 0.52680303E-03 0.18982373E+04
mu -0.34178657E+00 0.13495766E+01 -0.25325466E+00
eta is restricted to be zero
log likelihood function = 0.24824985E-01
LR test of the one-sided error = 0.18620315E+02
with number of restrictions = 2
[note that this statistic has a mixed chi-square distribution]
