I have a question (actually two). is it like this that the DEA (even SFA) can be used only to know the relative efficiency score not absolute (I mean one has to take more than one DMUs for comparative analysis). if say I say I want to look at revenue/Tax collection efficiency of a particular country I can't do that do I need to compare it with another country. ? Secondly suppose we have sufficiently large number of sample size which model is better to use than DEA or SFA ? Reply is much appreciable. thanks
You need multiple observations. Sample size is not the criterion that should determine whether you use DEA or SFA. The two methods do different things. Let me point you to facweb.knowlton.ohio-state.edu/pviton/courses/crp394/coelli_Intro_effic.pdf, especially chapters 6 and 9.
It was really helpful video for me but i face a problem while DEAP... i have 30 firms but when i get the result it only shows efficiency of 5 firms. can you please help in this issue?
i have a question. how if there are two input but have a different unit. input 1 labour and input 2 space. its mean that labour is called by unit, and space called by meter square. can i run my data with this circumstance? Thank you
Thank! I used to be confused a lot about DEAP before watching your video.
Hello! This lecture extremely helpful for my major project!
Thanks a lot.
Thank you very much. This is my lifesaver!
Muchas gracias por el tutorial!! Super útil!!!
This was very helpful thanks man
Great Video. Thanks
Thank you. You helped me too much.
Thanks! It was truly helpful.
Thank you so much!
very helpful thanks a lot! keep up the good work!!!
This was very helpful, Thank You!
Thank you. You helped a lot. But what about the curve building using data from out-file?

When do we use zero, one, two, three, or four
0=DEA(MULTI-STAGE), 1=COST-DEA, 2=MALMQUIST-DEA, 3=DEA(1-STAGE), 4=DEA(2-STAGE)
Thank you!
it's so helpful! thankyou so much
Thanks a lot for this information
Hey this probably will save me and make possible to finish my degree in Maths applied to economics. Thanks
Thank You
How is about the interpretation of the tested results?
If we have two outputs does first two excel column must be the outputs?
Could you please tell me if it can be used for DEA Window Analysis?
Please how to add big data of large firms because whenever i copy data from excel in notepad it all got disarranged.
tell me how to arrange data to get the result for more than one year
How much time will it take if I am analysing 9k firms with 5 inputs and 2 outputs using 1 stage DEA?
plz tell me how we select the no of firms??? it represent the number of rows?
can i use this for 1 firm only??but with 5 years?
Hello Sir, I would like to know the DEAP version you are using.
can i predict match and mismatch of inputs and outputs by DEA
dear i have data for more than on year so how can find the efficiency score???????
Hi, the software is showing te for all the firms as 1.00 which is not the case. It is taking the input and output correctly. Help please!
hi can we do DEA meta frontier analysis in DEAP 2.1? if yes how
It was really helpful video for me but i face a problem while DEAP... i have 30 firms but when i get the result it only shows efficiency of 5 firms. can you please help in this issue?
me too, I have the same problem
were you able to do it ?
Change the number of firms to 30 in the instructions file.
i have a question. how if there are two input but have a different unit. input 1 labour and input 2 space. its mean that labour is called by unit, and space called by meter square. can i run my data with this circumstance? Thank you
I read units dont matter.
does anyone know if this program is available for mac??
THANK YOU
Hello will gladly help you with your DEA project
hi, i did the DEA using a file with 110 DMUs, but i got no results.i don't know why
I have the same problem. The output file doesn't change from the sample. Were you able to fix this?
@@lillithvale7528 i have de same problem. how can you fix this?
I have same problem for 200 DMU
Thanks a lot. This is really helpful. Can you please shed some light on the interpretation of the result from the DEAP software. Great thanks.
hello and thank you so much for your excellent tutorial. is it possible to teach us malmquist command in stata, please. thank you very much
Hi all, i have downloaded the DEAP software, follow the procudure, it is not getting results
Results from DEAP Version 2.1
Instruction file = Eg1-ins.txt
Data file = EG1-dta.txt
in that output file, this is only i got it
