[pwl]

Hello. I do not have any experience in statistical programs and I want your help to run the DEA method on SAS.

On this site http://sas-or.com/book/?s=DEA  I find the code that I want to run.

The only that I do on the code is to change the below codes and put where is my txts files and the number of inputs,outputs and units.

%let _InData=’C:\sasor\Data9_2_In.txt’;
%let _OutData=’C:\sasor\Data9_2_Out.txt’;

%let _nInput=2;
%let _nOutput=3;
%let _nUnits=10;

But the code is not give me the results. 

Should to change something else on the code?

pls give me your advance. Thank you.

Are you getting any error messages in the log? If so post them.

You may also want to set the Option mprint; before running the code so that warnings and errors are placed in context with code generated by macros.
