I attempted to run malmq.ado using sample DEA data in Stata 11: [.malmq i_AC = O_SPI O_CPI, ort(o) period( period)]. This returns an error [3499 _uniqrowmat() not found].
I was unable to find any information on this command, which malmq.ado references. Can you let me know how I can get around this error?
Thank you in advance for your help.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
There are some possible reasons; didn't run "ldea.do" command properly before your malmq command, old versions of malmq.ado or dea.ado are not renamed or deleted, or Stata does not find the ldea.mlib.
Please try the following procedure again.
- command "discard" in your stata command window or reopen Stata program.
- delete or rename all the malmq.ado files.
- Save "ldea.do" file favorably in your working directory where your data exist.
- Open your data file using Stata program.
- In your Stata command window, command "do ldea.do" : you need to run this command only once before you run the mqlmq command after you open the Stata program. You can open "ldea.do"file using the Stata do file editer and quietly run it.
- Try your analysis using the attached data set. I tested it and got the result.
; malmq i_AC = O_SPI O_CPI,ort(o) period(time)
- If you still get the same error or another, please post them here again.
* Pleae note that all the previous versions of dea.ado or malmq.ado files need to be discarded and ldea.milb created by commanding "do ldea.do".
I have a different problem but the same error code. I can use the malmq command just find, but everytime I add the saving or sav command it comes out with an error like so:
<istmt>: 3499 file_exists() not found
I'm really stumped why this happens, any help you could give me would be nice. I'm running stata 12 if that helps
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Hello, I have the same problem: when I specify the option saving I get the error message : <istmt>: 3499 file_exists() not found.

You see the last one "ldea". If you don't have "ldea" in your list, it means
that your computer doesn't look the required library or you don't have
"ldea.mlib" file in your computer.
If it is the case, you can put the "ldea.mlib" file in your directory such
as 'PERSONAL' in my case and see if your computer finds it.
You can use the attached "ldea.mlib" file or generate by the command -do
ldea.do-.
Good luck.

You should get the above version of malmq.ado code.

First of all, given the tips in this forum I was able to run malmq code.
Now, I have doubts on the obtained outcomes that I hope to get some help. Considering 2 years of analysis (2012/13), with a balanced panel:
(1) In the first table, scores of t1 correspond to 2012, and t should correspond to 2013 right?
(2)In the second part, whith CRS and VRS, some units appears twice in 2012 but not in 2013, while others are twice in 2013 but not in 2012. What might be happening?
(3) Finally, in the last table where five indices are decomposed. Why are some dmus lacking?
Thank you in advance.

I'm now obtaining the same results as you've send me.
Yet, in the first set of results (Cross CRS-DEA Result) it seems that t in fact corresponds to 2013 if compared with the results of the following dea code: dea i_nrstaff = o_nrvisits , rts(vrs) sav(2012_2013) // crs column. I was wondering if you could check this, please.
Regarding your forthcoming article in The Stata Journal, you refer that using some summarizing statistics it will be possible to obtain efficiency catch-up and technology progress. Practically, how should I do?

=> the first set of results shows the technical efficiency scores relative

frontier of year t and the score is the technical efficiency score of dmus
relative to it.
I'll see if there is a problem later.
Regarding your forthcoming article in The Stata Journal, you refer that
using some summarizing statistics it will be possible to obtain efficiency

For your question "bootstrap method using the Gaussian kernel density
estimation and the bandwidth selection, are these just standard procedures
behind the used commands of dea?"
No.
I used the bootstrap method using the Gaussian kernel density estimation
because there was no available approach using stata with dea program.
So, I developed this program in Stata.
I and my research colleagues have programmed the two-stage bootstrap method
and currently testing it. It works fine, but due to my time constraints I
couldn't make any help file.

(1) In the first table, scores of t1 correspond to 2012, and t should correspond to 2013 right?
(2)In the second part, whith CRS and VRS, some units appears twice in 2012 but not in 2013, while others are twice in 2013 but not in 2012. What might be happening?
(3) Finally, in the last table where five indices are decomposed. Why are some dmus lacking?

Subject: [deas:discussion] Re: malmq error - uniqrowmat command
Thanks for your effort.
For prior checking, please see attached the .ado files and libraries that I
have in my personal folder, which might help to explain our different
results.
Then I simply run: malmq i_nrstaff = o_nrvisits, period(Y) sav(output_malmq)

Dear Choonjoo,
I'm now obtaining the same results as you've send me.
Yet, in the first set of results (Cross CRS-DEA Result) it seems that t in fact corresponds to 2013 if compared with the results of the following dea code: dea i_nrstaff = o_nrvisits , rts(vrs) sav(2012_2013) // crs column. I was wondering if you could check this, please.
Regarding your forthcoming article in The Stata Journal, you refer that using some summarizing statistics it will be possible to obtain efficiency catch-up and technology progress. Practically, how should I do?
Thank you so much.
Lucia

Dear Choonjoo,

code: dea i_nrstaff = o_nrvisits , rts(vrs) sav(2012_2013) // crs column. I
was wondering if you could check this, please.
=> the first set of results shows the technical efficiency scores relative
to technology frontier of t year. So, the program is coded so as to t is the
frontier of year t and the score is the technical efficiency score of dmus
relative to it.
I'll see if there is a problem later.
Regarding your forthcoming article in The Stata Journal, you refer that
using some summarizing statistics it will be possible to obtain efficiency
catch-up and technology progress. Practically, how should I do?
=> The following paper will give some ideas. I will get back to you later if
you are not clear about it.

Thank you for referring the abovementioned paper. I now understand the purpose. In addition, when in the article is mentioned bootstrap method using the Gaussian kernel density estimation and the bandwidth selection, are these just standard procedures behind the used commands of dea?

Hi~
For your question "bootstrap method using the Gaussian kernel density
estimation and the bandwidth selection, are these just standard procedures
behind the used commands of dea?"
I used the bootstrap method using the Gaussian kernel density estimation
because there was no available approach using stata with dea program.
So, I developed this program in Stata.
I and my research colleagues have programmed the two-stage bootstrap method
and currently testing it. It works fine, but due to my time constraints I
couldn't make any help file.
Choonjoo.

Ok, it is nice to know that. I'm looking forward to have this new procedure whenever possible.
Thanks,
