请教各位高手:在进行DEA二阶段的过程中,用frontier软件得到:the final mle estimates
其中的log likelihood function 是投入松弛变量吗?见下面
the final mle estimates are :
coefficient standard-error t-ratio
beta 0 0.90477440E+02 0.99941383E+00 0.90530506E+02
beta 1 0.10729887E+04 0.99999349E+00 0.10729957E+04
beta 2 -0.64549020E+04 0.99999997E+00 -0.64549021E+04
beta 3 -0.81379476E+01 0.91013490E+00 -0.89414740E+01
sigma-squared 0.29645454E+05 0.10000000E+01 0.29645454E+05
gamma 0.10000000E-07 0.16072471E-01 0.62218186E-06
mu is restricted to be zero
eta is restricted to be zero
log likelihood function = -0.58625853E+02
