Hi dude, nice explication, but this video left me with a question, why to check the normal distribution if this method to analyze efficiency is a non parametric method?
Thank you lot for this video. Can you tell me please how create y matrix with two or more outputs and with one year omitted for one dmu (unbalanced panel) thank you again
Slacks represent only the leftover portions of inefficiencies. After proportional reductions in inputs or increases in outputs, if a DMU cannot reach the efficiency frontier (to its efficient target), slacks are needed to push the DMU to the frontier (target).
Hi! very informative and helpful! i am wondering how to do the bootstrapped using FDH method, it seems like the benchmarking package not include FDH in dea.boot. Any comments will be helpful, thx in advance.
I have a sample with a few months of data and would like to estimate the efficiency scores for each month (Stock picking for portfolio). Do you know any command to do that instead of breaking data by month and do it over and over? Asking this for research purposes. Thank you in advance!
Please how do i solve this problem "There are data with very different orders of magnitude. Try to redefine the units of measure or some linear problems may be ill-posed"
Hello, I need to function(x) 1/as.numeric(x) so my results are "ok", do you have some suggestion to R return the right values and I don't need to function(x) 1/as.numeric(x)) ? Thank you so much

I am getting all efficiencies as 1 and dont know what to do I have checked using an Excel based plug-in of DEA which gives genuine efficiencies. Please help urgent, any help will be appreciated. Thanks in advance !!!

Hello sir, I tried bootstrapping DEA with CRS restriction. However, it keeps saying that "Error in set.row(lps, h, c(0, -XREFp, h])) : Model has not been optimized". Can you explain what causes this problem? I could do with VRS, though. Thank you in advance!
Sir can you please make one more video, interpreting the output from R

Hi dude, nice explication, but this video left me with a question, why to check the normal distribution if this method to analyze efficiency is a non parametric method?
Really helpful sir....... Thank you.
Thanks for the video. Why are my bias corrected scores worse than without bootstrap scores?
Make a video on double bootstrap method with truncated regression model by simar and Wilson 2007
Thank you lot for this video. Can you tell me please how create y matrix with two or more outputs and with one year omitted for one dmu (unbalanced panel) thank you again
First, thank you a lot for this video! It is very absorbing! I have a question what does slack means here?
Slacks represent only the leftover portions of inefficiencies. After proportional reductions in inputs or increases in outputs, if a DMU cannot reach the efficiency frontier (to its efficient target), slacks are needed to push the DMU to the frontier (target).

Asking this for research purposes. Thank you in advance!
If you are still in need of this just make DEA as a function and then make a for separating each month and then a combined table!
@@leonidaskyrgiakos6881 thank you. I am still learning how to use R
Sir, please help me by answering this...which method will be best for analyzing bank performance ???
DEA is widely used, see some latest journal articles.

I have followed the same steps. but it does not work. it says 'Error: unexpected '=' in "bcc

hi, will you have a discount coupon? I am interested in learning more about it. Thanks
thankyou so helpful
Glad it helped! Please share with your friends and colleagues.

Hello, where can I find the database (.xlsx or .csv), I couldn't find it in your website, even in the DEA-code.zip. Thanks in advance!

Hi, send an email to with a screenshot of you code and error.
Ziaul.
sir version not compatible, i am not able to copy codes
Can you help ?
Thanks in advance !
Sir, could you please make a video on SFA on R..
Sir can you please create r code for M input and N output variables
Pls see researchhub.org/store/dea-r-script/
Sir , can share the code of truncated regression
BCC and CCR are old models. They have lots of disadvantages.
Please make a video on newer models and send us the video at admin@researchhub.org; we will publish your video in our channel giving credit to you.
