Hello, I am using a data envelopment analysis module, dea, authored by Ji and Lee. http://www.stata-journal.com/article...article=st0193
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. Is this a known bug with a solution or update?
