Pls Help me for Data Envelopment Analysis method with SAS

[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.

My net nannies won't let me see that link so this is a guess. It is very likely that the in data set is expected to be a SAS data set already and the outdata is expecting a SAS dataset name as well not text files.

would you know what I must do for this?

Read the input text file into a SAS dataset.

Specify the desired name of the ouput data set in the output.

The output set could then exported to a text file or reports run on the output data.
