However, when I plug in my data and let it run, I occasionally will get back result with some of the DMUs having theta greater than one. This has happened on multiple occasions. That should be impossible in DEA. Also, on occasion, some of the DMUs will have a missing entry for theta, represented by ".". Is this a known bug with a solution or update? I am running Stata 14.
