Please run 'ldea.do' in the command window and see if you get 'ldea.mlib' file in your folder.
And check if you have the recent dea.ado file dated as of Feb 2014 by commanding -viewsource dea.ado-.
Since you don't have any missing value in your data set, you should be able to get the results.
If the above procedure does not help, I can check your data set if you send it to my private email.

Dear Choonjoo,
Thank you very much for sharing the files.
I wrote to you not last month to enquire about problems I encountered using the DEA command.
I downloaded the ldea.do file, opened it with STATA.
Then run the DEA analysis with my dataset.
However, I received the following error message.
But I have checked thoroughly that none of my variables have missing values.
Can you please advise?
Thank you very much!
Regards,
KK

Sir,
I want to do subvector dea analysis. Is it possible to do this in Stata?
What is the maximum number of DMUs that can be analysed in Stata?
