DEA Package Install Problem

[Tugba Kaynak]

Hello,

I am trying to install Data Envelopment Analysis (DEA) package in Stata 17, but I have encountered several problems.

1. I ran ssc install dea and ssc search dea, but I did not find an official dea package in ssc.
2. I found the dea package here: https://sourceforge.net/p/deas/code/HEAD/tree/trunk/
3. I downloaded dea.ado file and extracted the files to my local directory as C/ado/plus
4. Then, I tried installing with ado file in stata: do dea.ado, but it gives error while uploading the package as:
5. variable i undeclared
6. (344 lines skipped)
7. end of do-file
   
   r(3000);
8. Then, I tried to declare variable i as in mata: real scalar i
   command real is unrecognized
   r(199); or when I run:
9. real scalar x
   nothing found where '(' expected
10. I am using Stata 17 (64-bit Windows). I verified my Stata installation with about and there is no issue.

How can I install DEA package properly from SourceForge or any other source, could you help me?

Actually you have installed dea successfully if you put it into C/ado/plus/d.
1. dea is not stored in SSC, and SSC has no search subcommand. So neither ssc install dea nor ssc search dea could get what you want.
2. As you have downloaded dea.ado and put it into C/ado/plus/d, you will run it successfully.
3. You should download dea.sthlp and also put it into C/ado/plus/d, then just type help dea in your Stata command window.
4. You need not to do dea.ado

#4 was a misunderstanding and #5 to #9 were also misunderstandings.

I have never used dea or tried to install it, but your link shows several files and my best guess is that you need to install all the files. If you did that, good.

That done, your next step should be to type

help dea

to find out how to use the command. The way to use the command is never to type

do dea

expecting (perhaps) that you will get a series of prompts. That is not the way that Stata commands are written to be used; in principle they might be, but I can think of any.

I put dea.ado and dea.sthpl into the file C/ado/plus/d, then I run the command:

dea mr_scans total_applications
struct BoundCond undefined
(129 lines skipped)
(error occurred while loading dea.ado)
r(3000);

. dea mr_scans total_applications, returns_to_scale(vrs) orientation(input)
program mkDmuMat already defined
(error occurred while loading dea.ado)
r(110);

I still face the problem about installing.

I also run the command do dea.ado, while it was loading it gave the error in below line:
> maxindex(VM[2,], 1, mi, mw)
> LPRSLT[1] = VM[2, mi[1]]
> for(i=1; i <= rows(mi); i++) {
> LPRSLT[1+mi[i]] = 1
> }
> FDHRSLT = FDHRSLT \ LPRSLT
> }
> }

> return(FDHRSLT)
> }
variable i undeclared

end of do-file
