真要光去求解的话也可以做的~~我不清楚你的输入和输出分别是什么,我按照你txt里的前三组数据作为输出变量,后三组数据作为输入变量作了一下,4个样本都是DEA有效的。
不过从经济意义上来说,这样做意义不大,对于样本数n和指标数(输入指标m个,输出指标s个)有这么一个约定,即n>m+s+2。
但如果光从求解LP问题上来说,你的数据符合条件,可以求解出一个答案。只是实际意义不大。

Results from DEAP Version 2.1
Instruction file = 123.ins
Data file = data.dta
Input orientated DEA
Scale assumption: VRS
Slacks calculated using multi-stage method
EFFICIENCY SUMMARY:
firm crste vrste scale
1 1.000 1.000 1.000 -
2 1.000 1.000 1.000 -
3 1.000 1.000 1.000 -
4 1.000 1.000 1.000 -
mean 1.000 1.000 1.000
Note: crste = technical efficiency from CRS DEA
vrste = technical efficiency from VRS DEA
scale = scale efficiency = crste/vrste
Note also that all subsequent tables refer to VRS results
