求助~~~用DEAP软件算技术效率等为什么全部都是1？-经管之家官网！

各位大神，我用DEAP2.1软件算4家公司的效率，4个投入指标，2个产出指标，例如2005年： Y1 Y2 X1 X2 X3 X4

123.69	2.14	212.09	78	86.84	52.97
225.1	-	-	143	153.65	36.65
45.68	0.3	200	392	6.87	43.9
1.59	0	206.91	50	0.16	51.96

分别从2005年算到2014年，
运行的时候设置的是：
123.dta DATA FILE NAME
123.out OUTPUT FILE NAME
4 NUMBER OF FIRMS
1 NUMBER OF TIME PERIODS
2 NUMBER OF OUTPUTS
4 NUMBER OF INPUTS
1 0=INPUT AND 1=OUTPUT ORIENTATED
1 0=CRS AND 1=VRS
0 0=DEA(MULTI-STAGE), 1=COST-DEA, 2=MALMQUIST-DEA, 3=DEA(1-STAGE), 4=DEA(2-STAGE)
为什么每一年的结果运行出来显示都是这样？
Results from DEAP Version 2.1
Instruction file = 123.ins
Data file = 123.dta
Output orientated DEA
Scale assumption: VRS
Slacks calculated using multi-stage method
EFFICIENCY SUMMARY:

31.0001.0001.000-
41.0001.0001.000-

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
为什么所有的效率都是1？是我设置的有问题还是数据方面的问题。。。。有没有哪位大神知晓TT。。。。小女子万分感谢啊~~~~~~~~~~~~
