请问您的ins是这样输入的吗,gamma 0.80和 总方差0.22我在out文件里面一直找不到 您用的是ole 、grid search 还是final哪个呢 Thanks♪(・ω・)ノ

NOTE: IF YOU ARE SUPPLYING STARTING VALUES
AND YOU HAVE RESTRICTED MU [OR DELTA0] TO BE
ZERO THEN YOU SHOULD NOT SUPPLY A STARTING

Error Components Frontier (see B&C 1992)
The model is a cost function
The dependent variable is not logged
the ols estimates are :
coefficient standard-error t-ratio
beta 0 -0.54536404E-01 0.44593858E-01 -0.12229577E+01
beta 1 0.82722174E+00 0.64355780E-01 0.12853884E+02
beta 2 -0.58382461E-01 0.73136978E-01 -0.79826186E+00
beta 3 0.44989458E-01 0.82499979E-01 0.54532690E+00
sigma-squared 0.87690766E-02
log likelihood function = 0.77048956E+02
the estimates after the grid search were :
beta 0 -0.15361896E+00
beta 1 0.82722174E+00
beta 2 -0.58382461E-01
beta 3 0.44989458E-01

gamma 0.85000000E+00
mu 0.00000000E+00
eta 0.00000000E+00
the final mle estimates are :

log likelihood function = 0.10927265E+03
LR test of the one-sided error = 0.64447395E+02
with number of restrictions = 3
[note that this statistic has a mixed chi-square distribution]
number of iterations = 19
