Has anyone tried 'malmq2' to run a Malmquist DEA?

[Cool joe]

I am a new STATA user and tried to run the captioned but return with an error msg. malmq2 is a recently updated ado. I have read many posts regarding the previous version and seems many problems occur with the previous version too.

Can anyone give me suggestion?

For a function, it was not already loaded, it is not in
the libraries, and there is no .mo file with its name.

The output of search malmq2 gives the email address for the author, who perhaps can address your problem.

Hi, I had exactly the same problem. The 'malmq2.ado' file is in the subdirectory that hold ado files, but I got the same message as you did. If you are able to find out how to fix it, I am interested to know.

There is a newer version of malmq2 which fixes the problem. Find it at: kerrydu.github.io.

Thank you for reporting this back to Statalist. I have added this new information to a Statalist topic that contains a running compendium of issues around the dea and malmq commands at
