标题: SAS做DEA！急
我运行了一个SAS算DEA的代码：data dea;
input _id_ $x1-x9 c s1 s2 s3 _type_$ _rhs_;
cards;
object ......... 1 -1E-6 -1E-6 -1E-6 min.
input1 3.80 4.00 4.00 4.00 5.00 4.00 4.00 6.00 5.00 -3.80 1.. eq 0
input2 1.63 2.30 1.80 1.83 2.07 2.75 4.40 1.65 1.77 -1.63 .1 .eq 0
output 0.99 1.00 2.26 1.24 0.91 0.81 1.76 2.50 1.56 ...-1 eq 0.99
;
proc lp;
run;
错误：8 ;
ERROR: The SAS/OR product with which LP is associated is either not licensed for your system or the
product license has expired. Please contact your SAS installation representative.
9 proc lp;
ERROR: Bad product id for procedure LP.
10 run;

我想请问LP是SAS自带的函数还是要自己编的？
很急！如果谁有SAS算DEA（CCR）的代码，传份给我好吗？不胜感激！
