Hey Abdul, I found your video very useful! I am working on a thesis on cost efficiency in hospitality and had to figure out this method myself, and I have a much better understanding now. Thank you!
Thanks a lot! Really appreciate the great effort you've put in to simplify DEA. I've watched it once and will watch it again tmr, and probably day after tmr, and probably... It's not an echo... This seems hard, but your video provided a glimmer of hope!
very simple way of explaining the DEA analysis i will encourage you to keep on ..you make it to simple and understandable ..better than even my prof when i was at university ...simplicity is the best way of explaining many complicated formula analyis ..once again keep on..
So, I am not trying to be critical here. I am trying to understand. Maybe I am missing something easy. Between the 5 minute and 6 minute mark, he concludes that A is efficient, and I assume (I don’t believe he ever explicitly mentioned it) it is because the more discharges the better, and the less operations the better, and A betters B and C in both cases. Between the 6 minute mark and 8 minute mark, he concludes that B is inefficient because he took a linear combination (50 % weighting for each) of A and C. HOWEVER, 85 operations is “WORSE” than 50 operations, so I don’t think he can conclude that, can he? Then between the 10 and 11 minute mark, he says something about the line AC lying above AB and BC which means “this is more desirable than this”- or something to that effect. But now, it seems he is comparing LINES to other lines, and don’t you want to compare POINTS to POINTS? I would think that for a case (which is a point, such as B or C) to be INEFFICIENT, you would only compare points, and if the point (such as B) was to the left-less discharges -- which it is…and ABOVE - more operations - which it is NOT), then it would be shown to be inefficient. But it seems to me that V is not more inefficient since it has more operations. What am I missing here?
Nice contribution brother, please ignore the negative comments on your video, everyone watched because it worth for us. Please keep posting also on SFA and other
Hi Abdul, I will be needing your assistance, your explaination is effective to my educational journey and personal development. I appreciate your expertise at explaining the Output and Input data analysis for decision making. Thank you! :)
Dear Abdul! Very good explanation. But one thing I want to clarify in the composite (or combined) equation you said ʎA *A+ʎB*B such that ....................I think there should be ʎA*A+ʎC*C.
the content itself is good and explains the DEA very well. However, the pause and "um" in the presentation is quite distracting. I suggest use 1.5 times speed to listen to this presentation and it works great. overall, great content and thank you for sharing ! Keep it up :)
Thanks fro such enlightening lecture. i want to ask you one thing. can we use this approach to identify the efficiency of every thing. let me say for example tax/expenditure efficiency of a particular country. second question i have read DEA all the time with respect to pannel data can we use time series data aswell ? looking forward for your reply
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
Hi, thank u so much for this intro it help me to understund much better, im using this approach in the efficiency of education, can u give me some issues to use DEA in STATA
10 років тому+1
thank u very much, but i didn t get how could u find 6,3 doctors :s did i miss something :S i m sorry but if u can reply me i ll be so grateful
Dear Betül, You have an important point. However, in this case, there is no problem since you can think of 6 full-time doctors and a part-time doctor covering about 1/3 of a full-time doctor time. I hope this addresses your point.
Great one to start learning Data analysis , I really appreciate this kind of effort

Thank you for your easy to follow explanation, Abdul!
Simple and Good example to Introduce DEA to beginners
The practical example in the beginning was very helpful
So, I am not trying to be critical here. I am trying to understand. Maybe I am missing something easy.

Simple, easy, a great job and good effort man thank you it really helped me man, salutes from Mexico!!!
Great video, greetings from Germany🙏🏼🙏🏼
Thank you for your good explanation. it is clear and easy
Thanks for a very nice introduction. I like it because of its clarity and simplicity.
Dear Abdul, It is a nice job! keep it up!
Thanks for your easy to understand explanation.
You are amazing! Pls make more videos! I understood everything!
Excellent explanation of DEA.
Thanks
thanks man its really helpful, for people watching they can increase speed upto 1.5x and it would save you time.
Nice contribution brother, please ignore the negative comments on your video, everyone watched because it worth for us. Please keep posting also on SFA and other
Thanx man, you helped me a great deal!
Thank you
the video is helpful to my project.
Very nice! Excellent! Thanks much.
Hard made easy....thank u for uploading. God blss u
Thank you so much! your explanation is very effective!
Well presented, Sir!
very good, Abdul. Greetings

THANK YOU. IT WAS CLEAR AND PRECISE
Thanks very much for this introduction video! It helps!
Thanks, it was so helpful
Hi Abdul, enjoyed your DEA explanation. It is simple and clear and makes the working of DEA understandable and easy.
Cheers
Thank you so much! from Colombia
It was clear to me and he seems like a friendly guy also.
Thank you very much for your effort.
It's so helpful for me,thank you so much

Your video gave a good intro to DEA. I have a doubt here. How do we calculate Lamda_A and Lamda_B?
Very helpful. Thank you
Thanks for your video of DEA. Have you have used the DEA Solver of Excel? If you use, can you explained the outputs of the software?
waaw!! the somali guy,, i realy enjoyed with ur nice explanation....
This video helped so much! Thanks
explained in very lucid manner and with simple example.
Great video, brother. It's been long, I hope you do better in presentation now.
Thank u for ur lesson

Thank you very much bro !
Good job!
Well done!
How calculate the 6.3 doctors
Is slope
Hi Abdul! Thanks a lot! Please could you clarify How do you calculate 6.3 ?
Thanks for appreciating:-)
Dear Abdul I cool I get in touch with you ?
DEar Dr. Abdul can you give us the explanation when it's input oriented
Hi, thank u so much for this intro it help me to understund much better, im using this approach in the efficiency of education, can u give me some issues to use DEA in STATA
thank u very much, but i didn t get how could u find 6,3 doctors :s did i miss something :S i m sorry but if u can reply me i ll be so grateful

thanks for your kind explaination, but i am a bit confused between scale efficiency and allocative efficiency so can you explain that to me please?
Muito obrigado!
Thanks.
I can understand, but he's unsure about what he's trying explain.
Please, man, put subtitles... It would help so much!
But, yet, great video.
Thanks
Thanks for the video... but it really is horrible.
he himself is confused about the subject. He should prepare himself well and then come in front of camera.
Ugly presentation. But keep up though!
Man, I cannot understand a single think. please, try harder the next time
