求助！跪求各位大牛，要怎么用frontier呢？本人想用三阶段法，但是卡在第二阶段。-经管之家官网！

第二阶段的SFA是根据第一阶段的投入松弛变量为因变量，然后环境变量为自变量吗？具体应该怎么操作呢？10个公司，一年，产出变量一个，投入指标2个，环境变量4个，这样子软件应该怎么做呢？第一阶段得出两个投入指标的松弛变量：

人员松弛变量	资金松弛变量
1.990000	87.350000
0.000000	0.000000
6.580000	420.690000
5.730000	314.120000
1.660000	82.760000
6.040000	233.510000
0.000000	0.000000
3.620000	267.590000
8.180000	366.310000
0.000000	0.000000

环境变量1	环境变量2	环境变量3
27.780000	4.870000	5.120000
32.500000	4.690000	4.850000
40.000000	4.540000	4.220000
35.290000	4.690000	3.810000
39.130000	4.690000	3.990000
31.710000	3.970000	3.660000
18.750000	3.680000	3.660000
41.380000	4.430000	4.040000
27.500000	4.210000	3.460000
60.000000	4.420000	3.780000

输入是这样对吗？
1.000000 1.000000 1.990000 87.350000 27.780000 4.870000 5.120000

这样选择对吗？
