Hi, Laura,
Maybe you can try following free software developed by Coelli.

Subject: st: DEA Inefficiencies
Dear Statalist,
I am trying to compute DEA inefficiencies for multi-outputs (3)
multi-inputs (7) production function with constant return to scale of
hospitals.
dea $inputs = out inp art, rts(crs) ort(in) stage(1) saving (dea_crs)
When I run this command for a small subset of the data, Stata gives me the
efficiencies.
However, when I run the command on the full dataset, Stata never stops and I
don't get any result. My panel dataset is composed by 128 hospitals observed
for 5 years.
Can you help?
Thanks,
Laura
