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
