Hi dear list members:
I am runnigg a research about the productivity of hospital services.
Runnig DEA model, i found that in one of the years there are two DMUs with
the same Technical Efficiency and global technical efficiency as well as
non incresaing returns to scale technical efficiency, and they are not
efficient units.
This is the first time i find this case.
Can anyone give me an explanation.
Thanks
Jose
