The goal of this project is to develop a Data Envelopment Analysis(DEA) program using Stata programming language. This is the replacement of "deastata" project that we maintained for the purpose of version management.
We call the program package "DEAS" which stands for Data Envelopment Analysis using Stata.
DEAS covers the basic models of DEA and extensions including CCR, BCC, SBM, Super-efficiency Model, Allocative Model(Profit, Revenue, Cost), (Global) Malmquist Productivity Index Model, Imprecise DEA, FDH, Additive Model, Virtual Price Model, linear programming(lp), mixed integer linear programming(MILP), and more.

Can you please provide me a pdf/ instruction on Slack Based Model(SBM) using DEA in Stata? I am really looking forward to it.

Dear Chonjoo lee. Thank you very Much. I have some problem about "dea_allocative" module. I would be grateful if you could help me. 1- Profit efficiency model yields different results using "val" and "unitvars" options. 2- The "rts" option is not work with profit efficiency model. 3- In the case of DMUs with negative profit (loss) how i could interpret profit efficiency? 4- model(p) do not report Allocative efficiency. Best Wishes mohamad here is my obtained results using dea_allocative, model (p): . dea_allocative t l s c fr w = y, mod(p) unitvars(pt pl ps pc pfr pw py)
